using unity animation, Is there a way to offset UV of only one material?

Hi !

I have a 2d character, I use a material for the head and other materials for the body. The material for the head has one texture. The texture is an atlas of different faces. I want to swap the face during an animation, that's means offsetting the uv of the material.

I found two differents approach for this problem and none is satisfactory for now

1) I can create a event during the animation, a trigger for a script that call something like

GetComponent<SkinnedMeshRenderer> ().materials [0].mainTextureOffset = new Vector2 (0.5f, -0.5f);

That's is working. The problem for me is that:

• is asking for a script and I would like to said in the animation, so that my artist don t bother a coder every time they need something.

• it is a problem when blending animation, since the trigger can be missed completely if I don t start the animation at the beginning

So I tried using the animation system a bit more.

2) I have added a Property for Skinned Mesh Renderer.Material._Main Tex_ST ( using the add property button) then I've changed the value z and w for this properties.

This works except it change the offset for all the material on my object, so its messed with the other part of the body.

Question: Is there a way to offset a texture for only one material using the animation view ?
