Question Emissive texture Realtime GI update

I am able to change the material Emissive texture in realtime, but I can't update realtime GI accordingly.
This is the original mat emissive value (without texture), the game view and the lit clustering view:

If I change the emissive texture in Editor mode, game view and lit clustering are changed in the right way:

But if I start from the material without emissive texture, and in realtime I try to change the emissive texture, I obtain this:

as you can see, lit clustering is wrong. To update emissive texture I did this (i'm using the standard shader):

Code (CSharp):

1. MeshRenderer.sharedMaterial.SetTexture("_EmissionMap", NewEmissionMap);
2. MeshRenderer.sharedMaterial.SetColor("_EmissionColor", White);
3. DynamicGI.SetEmissive(MeshRenderer, White);
4. RendererExtensions.UpdateGIMaterials(MRenderer);
5.  

Am I missing something?

 

Anyone?

 

Up!

 

Sorry guys. I really can find anything on this argument. Is it possible that I am the only one that is asking something on this topic? O_O

 

I'm not expert in this area but realtime GI is actually precomputed realtime GI, meaning it saves data when you bake to be used in realtime later. So if you change materials with emissive textures in realtime it won't be correct when you play because it wasn't baked like that in the first place. Not sure what you're trying to achieve but maybe you should take a different approach.

 

AFAIK the real-time GI only works for lights, not emissive textures. Which makes sense, since it's done on the CPU and sampling textures would be very expensive, so it pre-calculates surface information instead.

 

Emissive textures work for realtime GI too, you just have to set its Emissive Intensity value above 0.

 

You're right. But... have you figured it out how can I update at runtime the precomputed realtimeGI for an emissive texture that is changing?
