Per-instance material color for entities?

I have an entity that I would like to be one of two colors depending on its state.
I.e. it will change from one color to the other occasionally.
Is it possible to do this efficiently, and if so - how?

Is this the way? Any sample script and prefab that demonstrates how to use it?

Thanks!

 

I asked that question here https://forum.unity.com/threads/how-to-change-color-of-material.874921/ and apparently you can not really do it well without using URP/HDRP.
Here I found some sample code to do it with the built-in renderer, but I guess that would be bad perfomance wise if you do it often on many entities: https://reeseschultz.com/pointing-and-clicking-with-unity-ecs/

 

Thanks. What would be the downsides of using HDRP for this?

 

Really do not know, but from my POV mostly that a lot of shaders and I think particle systems will not work and you have to have new ones.
I have seen some assets being updated though, so it may or may not matter to you.
Also of course if your doing that stuff by yourself I guess you can just make it so that it works, but me i do not have a clue how to write shaders or make particle effects that look good.

 

Main downside is a lot of assets on the asset store are not calibrated to HDRP. However, assets designed for the standard shader are also calibrated for URP, so it is only custom shaders for the built-in pipeline that don't work.

Code (CSharp):

1. [MaterialProperty("_Fade", MaterialPropertyFormat.Float)]
2.     public struct FadeProperty : IComponentData
3.     {
4.         public float fade;
5.     }

Code (CSharp):

1. Entities.ForEach((ref FadeProperty fade, in TimeToLive timeToLive, in TimeToLiveFadeStart timeToLiveFadeStart) =>
2.             {
3.                 fade.fade  = math.saturate(timeToLive.timeToLive / timeToLiveFadeStart.fadeTimeWindow);
4.                 fade.fade *= fade.fade; //Gamma-tize the fade
5.             }).ScheduleParallel();
