How To Make Changes To Multiple Objects In Blender That Are The Same
Learning Blender 3D multiple materials (optional)
Equally discussed in the previous section of this Learning Blender 3D tutorial series on making and applying materials to meshes, although multiple materials are not required whilst making the tutorial chair, it is useful to get over at this subject whilst we're already discussing 'materials' in general.

Much of the gear up-upwards and use of multiple materials on meshes and models is the same every bit with unmarried materials in that each separate textile is equanimous of the aforementioned core elements - "Textile", "Texture" and "Image". Where they differ is in how they are physically applied, and so that's largely what this following department will cover.
Assigning materials to faces ^
When using multiple materials on the aforementioned mesh object, each individual material has to exist physically assigned to the polygons and faces information technology's should affect. This means that much of the application of materials (and making of tin and) is washed in "Edit" mode. So, equally the mesh already has a single material applied from the previous section of this tutorial we need to make sure that it's assigned to all surfaces of the mesh.
Select the object and if non already selected and press "Tab" to enter "Edit" style; if the "Material" panel isn't visible after doing this click the sphere icon in the Properties Header. Looking at the at present available options, on further inspection there should be a new ready of buttons[ane] - "Assign", "Select" and "Deselect" - these are material consignment and direction buttons that allow individual materials to be assigned to different faces or sections of an mesh.
What we need to do at this bespeak is select the material from the list, select all faces of the mesh ("A") and then click the "Assign" button to utilize the "chair" fabric to everything (shown below).
Multiple cloth buttons. 1) the "Assign" button attaches selected material to a mesh or selection of faces [see *.blend "13c"]
Making a new material ^
Next, a new material needs to be fabricated and practical to other selected areas of the mesh.
Of import: using Blender ii.57 or above (up to and including the latest versions)? Skip ahead to the 'Annex' to learn how to add together new Material properties.
Still in Edit mode, click the "+" (plus) button to the correct of the material listing[2], creating a duplicate or copy of the original fabric[one]. This now ways there are two instances of that original material, indicated by the duplicate proper name in the material listing[1], which at present shows two entries named "chair", and by the presence of the number "two" to the left of the datablock name[3] (shown below).
Making a new fabric by copy/duplicating the default. 1) Textile list showing original and duplicate material. ii) The "+" button is used to create a new version or duplicate of the original material. 3) The new duplicated fabric datablock name "chair" [see *.blend "13d"]
The new duplicate then needs to be converted into a 'unique' fabric so simply a unmarried instance of it and the original be, both then being what are usually referred to every bit "single user" datablock's in Blender.
Design notation: a "datablock" in Blender is simply the name given to a segment of information that tin be used on its own, a "single user", or several times, a "multi-user", pregnant the more one detail or object is using the information associated with that "datablock", a texture used by several materials for example.
To practise this, make sure the duplicate is selected in the material list[1] (LMB select), then click the "+" push button[ii] to the right of the materials datablock name[3] ( non the "+" to the correct of the textile list every bit was done higher up). Blender will then convert the material and append an incremental number, starting with ".001 ", to the datablock, making information technology unique - the material list window and the datablock name will update to reflect this change, renaming the material datablock[3] to "chair.001" which is displayed in both the material list[1] and the material datablock name field below it[3], every bit shown beneath.
Making duplicate materials 'unique'. i) New textile automobile-named as a result of beingness made 'unique'. 2) The "+" push creates a new 'user' making the fabric unique ('single user'). 3) Material datablock name showing the default automatically named "chair.001" [encounter *.alloy "14"]
This new unmarried user material can then exist renamed in exactly the same way equally was done with the original by alteration the text in the datablock input field[iii], in this example to "back" (shown beneath).
Design note: it's all-time to rename these auto-named blocks considering the appended ".001" etc, can cause bug if meshes are exported to other formats for use outside of Blender.

Addendum: Adding new Materials in Blender 2.57+ or above ^
A major modify introduced to Blender 2.57+, and carried forward into newer versions, in the manner materials are managed ways we need to modify what we do when adding new slots. Instead of a new material beingness a duplicate of a previous datablock (set of parameters), in newer versions of Blender all this does is create a 'bare' entry in the Textile list - it has no default properties of whatever kind assigned past default[4]. To set this click the "+" button top-right of the Textile List view[one] and create the necessary new entry, as mentioned a 'blank' slot volition appear[2]. This so needs to be made 'unique' (single user) so it has it'due south own associated properties. To do make sure the new entry is selected in the Materials List and then click the "+ New" button[3], this 'converts' the reference into full Textile with a default set of backdrop that tin be assigned to the mesh as per beneath.
Click the "+" button[ane] to add a new material, this creates a completely blank cloth slot[2], it'southward neither a full material nor does information technology have any associated properties[4] - at the moment it'south but a data reference. Click the "+ New"[3] push button, this will 'catechumen' the reference to a fully contained (single-user) and named material, with it'southward own set of default options [run across *.alloy "13-257a"]
The entry in the Material list changes to reflect the change in 'state' of the original 'reference' once it'due south been 'converted'[ane] into a proper Cloth[ii]. A set up of default properties are now available[3]. i) Material ID datablock - proper name can exist changed. 4) In one case the material has some 'properties' it can exist assigned to the mesh
Once the material slot is ready properly it can then be assigned to the object past selecting various elements[ii] and clicking the "Assign" push button[one] - note the "Diffuse" colour[three] has been inverse to make the material and where it's assigned more than visible (shown in green to distinguish from previous instruction). 4) Fabric List entries showing the new fabric colour sample
Assigning multiple materials ^
In one case the bones parameters take been set, the fabric can be assigned to the mesh. Select a drove of faces (border, circle or Shift+RMB select), make sure the cloth is agile in the fabric list (" back ")[1] so beneath that, click the "Assign" button[2] to assign it to the mesh. The upshot of doing this won't be visible just still because both the new and original material currently use the same "Diffuse" color - ane or the other will need to exist changed[4] past selecting a new colour from the colour bike[five], the changes and so show on the mesh distinguishing each individual material assignment (equally shown beneath).
Design note: multiple materials are useful for managing the modeling process considering mesh sections can be shown or hidden based on material assignment.
Changing the new materials diffuse colour to get in more visible. 1) Textile list showing active materials. 2) Material assignment push button announced on entering Edit mode. 4) Irresolute the materials "Diffuse" colour to make it distinguishable from the other material applied to the mesh. v) Selecting the diffuse "colour" using the colour selector (which appears after clicking the diffuse colour sample)

Multiple materials and textures stages ^
Although the two fabric stages are now independent, the 'texture' and 'image' data (datablock's) associated with each is still the same[i], so in a similar fashion to the process described above, both of these references tin be converted into 'single users'[3], allowing for the assignment of different texture and image information to each material and making them both 'unique'.
Of import: using Blender two.57 or above (up to and including the latest versions)? Skip ahead to the 'Addendum' to learn how to add together new Texture backdrop.

Original texture phase with multiple users. i) Bachelor and used texture slots available in this stage of the overall materials fix-up. 2) Texture datablock proper name. 3) The "+" button makes a 'unmarried user' texture when there are more than ane reference being made to a texture
Editing and managing texture and image based material settings is done in the "Texture Properties" panel, so click the "Texture" button in the Backdrop Header (has a 'checker' on information technology) to open the appropriate options. To make the texture data 'unique' click the push numbered "2" or the "+" button to the correct of that[iii], this volition create a 'unique' texture by duplicating the original, motorcar-renaming information technology "Tex.001"[1] - where ".001" is an incremental number and "Tex" is a duplication of the original texture data and then it uses the same 'name' (bottom image below).
This newly created single user texture datablock ("Tex.001") can then be renamed by amending the text in the datablock input field[four], in this instance to "back"[5], completing the creation of a divide 'texture slot' for the previously created material. This now means that both the blue and xanthous materials use independent texture slots. Next, a separate paradigm has to be assigned to the new texture slot.
Making 'unique' texture stages from a multi-user datablock. 1) Texture slot listing showing the newly created unique texture. 2) The texture datablock automatically named "Tex.001". 3) The "+" push button creates a unique user from a indistinguishable. 4) Renaming the new unique texture to "dorsum". v) Texture list showing the newly created texture
Multiple texture stages and images ^
At this indicate at that place are ii separate cloth slots referencing two independent texture slots that withal use the aforementioned concrete image[ane][2]. This needs to be changed and so that, as before, at that place are two unique image 'users' with their associated bitmaps.
Continuing on from previous, scroll downward the "Texture Properties" options to the "Image" section[1] and instead of clicking the "+" push button as we've done before, click the 'binder icon' to the right of the datablock name[ii] to open up the "File Browser". Select an image - bank check whether the source material should use "Relative Path" - then click the "Open up" push to load the file. Doing this will automatically create a new single user image slot, so the "2" volition disappear[2] and the text associated with the datablock will display the name of the new image just loaded, "WOODgreen.tga"[1]. The "Preview" pane will too update to evidence a visual sample of the image - a 'greenish' tinted wood texture[three] in this particular instance.
Loading in a new image. 1) Image datablock name. two) File Browser push used to load in a new replacement image
Loading a new image into the previously created texture slot for the additional material
A 'unmarried user' slot loaded into the previously created unmarried user texture slot. 1) Image datablock name showing the image file "WOODgreen.tga". 2) File Browser push button to load in a new image. iii) New image loaded into the "Image" slot of the "Texture" [see *.alloy "17"]
To check the overall material has been fix correctly, view the "Textile" properties options, there should be two entries in the fabric list[1], "chair" and "back"[2], the pick of which should change the preview sphere to reflect the dissimilar images associated with the individual texture stages of each unique cloth[4]. In that location are at present 2 materials each has split "Material", "Texture" and "Image" slots.
Last materials, textures and images listed, all set equally unique (single) users. one) Fabric list showing the now two unique (single user) materials (with texture/paradigm preview). ii) Material datablock names associated with each material. iii) Diffuse colours assigned to each material. 4) Preview of the separate texture images associated with each material [meet *.alloy "eighteen"]
Shown for reference, the separate textures assigned to their respective sections of the UVW map [see *.alloy "18b"]
Addendum: Adding new Texture slots in ii.57+ or in a higher place ^
The change to the material system introduced with Blender 2.57, and carried into later versions, likewise means we demand to modify how "Texture" slots are made. On creating a new "Textile" (see previous), it's linked to a corresponding "Texture" slot[1]. At this point, this is but a 'connection' betwixt the 2 and then we know we're editing the correct 'material/texture' matching pairs. Every bit this is just a 'link' information technology too means the slot contains no "Backdrop" or texture data[3], so we'll need to add those in guild to then load in an paradigm and edit diverse settings (equally needed).
To add a new texture click the "+ New" push[ii] (first image beneath). This creates the necessary slot and populates it with "Clouds" equally the default texture 'type' (2nd image below') which nosotros can at present edit. Click the "Type:" drop-downwards[2] (third epitome beneath) and select "Prototype or Movie"[2] from the list which will then activate the "Preview" pane and "Image" sub-sections. To complete the texture fix scroll down to and in the "Image" sub-section click "Open" to load an image - in the File Browser (fourth below), select the file, prepare "Relative Path" and then click "Open Image" to load the file into the texture slot. The Preview pane and Image properties sections will update to show the new asset and file data.
Although any previously created 'new' material at present has "Fabric" properties, its "Texture" properties are blank[i,iii]; they have to be added by clicking the "+ New" push button[2]... [see *.blend "thirteen-257b"]
...which creates a unique (single-user) slot named "Texture" (shown in the texture slot list). This also creates a set up of associated backdrop that default to "Type: Clouds"
With the new backdrop added[1] select "Image or Movie"[2] from the "Type:" list to activate the textures "Image" properties and click the "Open" button[3]
In the File Browser select the image to load and make sure "Relative Path" is set. 1) click "Open up Epitome" to load asset. two) select the alphabetic character corresponding to your hard drive and select files/folders
In one case an additional image has been selected and loaded the "Image" backdrop will update appropriately to prove preview[3] and file information[i,2]. four) material applied to the mesh. 5) original fabric assignment
Terminal 'multiple' Materials showing the Material List entries[1], Material ID blocks[3] where the name tin be changed is required, the "Diffuse" property[four] where the colour can be changed, and the consignment push[2] to apply materials to the mesh (selections)
Using additional materials ^
Setting upward more than materials uses the same principle of duplicating an original global textile, assigning that to the corresponding faces or a mesh and then changing the data associated with the material and so it'southward using unique or single users per stage; if using separate images yous should e'er end upwards with a set of "Material", "Texture" and "Image" stages to the consummate global fabric.
With Blender 2.57 and across (including the latest versions) however, multiple materials take to be thought nigh in a slightly dissimilar way considering by default, each new entry is 'unique' rather than being a duplication of a slot that already exists. If duplication is required, once the new fabric has been ready it can be given the same properties associated with other materials by either manually setting them or selecting a previous entry from the "Browse Textile to be Linked"[two] property (the sphere to the left of "Material ID"[ii] input field) - simply LMB select the material to be changed from the "Material List"[i], click the 'sphere' and select the appropriate datablock. The material will update with the new settings whilst maintaining information technology's 'unique' status (information technology's still usable equally an independent material).
Select the MAterial to exist changed and click the 'Sphere' push[2] to open the "Browse Material to be Linked" information list. Click a previously entry. This assigns that datablock to the selected material in the Material Listing[1] which will then update the material and any assignments on the mesh [run across *.alloy "13-257c"]
Note that in assigning different material data, the currently selected material (the ane being assigned duplicate data) changes to reflect the chosen datablock[1]. This changes fabric 'data' simply[two] as the Cloth itself[iv] is still unique and so can be assigned and selected individually using the "Assign", "Select" and "Deselect"[3]
