Textures & Shading Tree: Material Nodes

[JayH]

Hi,

I'm a little confused as to the workings of Vray 3 for Blender, it seems to behave a little different to stock blender on two things I've noticed.

Single User Copy
When I create a material in stock blender, I can duplicate that material by pressing the “click to make single user copy” option. Then I can then independently edit that material, it won't effect the original.

This is very handy if you've created a material that you want to modify for another object.

In Vray there is an additional “Shading Tree: Material Node” option within the material properties that is available. Even if I duplicate the material as before, the 'Shading Tree Material Node' does not alter.

I end up with a copy of the original, but if I change it, it will change the original too.

Textures and Shading Tree: Material Nodes
They are not being removed if you re-use a saved scene. There may be times when I re-use a scene for one reason or another. But even it the objects in the scene have been deleted and I haven't used the option “Save this datablock even if it has no users” the textures are still listed in the UV Editor and the Shading Tree: Material Nodes are still available.

Shouldn't they be removed if they're not used?


Am I doing something wrong here guys?

Cheers, Jay.

Just press "+":

This is how it works, V-Ray data must be "Fake User". There is a tool under "Node Tools" - "Remove Unused Data" but may be it need some more deep cleaning capabilites...

I understand the method now thanks, it's a shame you can't re-name the Shading Tree: Material Node title, i.e. a material named "Blue" will name the Material Node "Blue.001" when copied, even if I change the actual material name it stays the same.

Shame it doesn't pre-empty automatically, or rather there was an tick box to empty unused if you forget.

It means there is already a tree called "blur", but there is a button "ab" near the tree name, it'll rename tree to material name.

Now add that to the manual

Thanks.
