Set Material Trouble....

BoYing

I use matertal.SetColor("_Color", Color.red);
If my asset is a skeleton animation clip it worked.

But when my assets is frame animation clip created by spine ,and use matertal.SetColor("_Color", Color.red); it doesn't work,
it seems change back to Color.white at next frame, how do I make it still stay Color.red by code?

Somebody help... March or anyone :doh: ?

(1) If you are using Spine/Skeleton, it doesn't have a _Color property so this would have no effect.

(2) If you access MeshRenderer.material, it will create a COPY of the shared (asset) material and assign it to itself. But MeshRenderer materials are under the control of SkeletonRenderer.
You can read more about that and the solution here: Spine-Unity Runtime Documentation

Basically, instead of saying

material.SetColor("_Color", Color.red);

You should use MaterialPropertyBlock. This is ideal for other situations too.

MaterialPropertyBlock mpb = new MaterialPropertyBlock(); // cache this in an instance field instead of a local to avoid alloc.
mpb.SetColor("_FillColor", Color.red); // "_FillColor" is a named property on a hypothetical shader. 
GetComponent<MeshRenderer>().SetPropertyBlock(mpb);

I had rewrited the Spine/Skeleton so it had a '_Color'.

Thanks a lot ! Pharan .

I fix it by use MaterialPropertyBlock , It is the best way! 😃
