Hi everyone, I want to set property for material, but I realize that the material instance is changed during the animation, this lead to the property I set before is disappeared. I know I can check if (previousMeshHashCode != currentMeshHashCode), then set those properties again, but I wonder if there're any official way or API to do this thing?
By the way, I realize most animations only change material one time at transition time, I quite understand why the material need to be changed. But there're some animations that change material
few time in an animation. If the material is changed quite frequency like that, I think it can be a hit to performance. Are there anyway to reduce that?
Set material property during the animation
@nam_nguyen Please see "I tried assigning materials at the MeshRenderer, but it is not possible. Why?" in the FAQ section:

If by the above sentence you mean that the materials change between frames, why would that be bad for performance?
If you mean that you are having multiple materials alternating at a single skeleton in a single frame, please see the linked documentation about Materials above.

Thank you, this's exactly what I need

I just afraid about creating new instance of material too often. But because I don't know how much it can hit to performance so I will ignore this until there're significant to the performance. Thank you so much.

Oh, you mean creating Material instances each frame. That would be bad indeed. When using the spine-unity runtime in the intended way, no Material instances should be created. If you see material instances as a result of setting custom Material values (like tint color), likely you should:
- a) only prepare your material once, or
- b) use other ways to set material properties every frame as described in this documentation section.

I have successfully made it not re-created anymore. Thank you so much
