Mask that is not re-calculated every frame.

Unity Engine
1

Hey.
Im working on some controls for my new shader, and want some fancy noise to be used as a mask on it.
However since this noise is quite GPU/CPU intensive and will only need to be controled between levels, i would love to have it only evaluate this code once i ask for it and then keep that stored untill i want to re-evaluate it.

So my question is, is there a way to generate a texture map in-game that does not need to be re-calculated every frame?

I suppose it’s just a matter of disabling the renderer (renderer.enabled=false) on the OnPostRender function of your texture generator. Then you re-enable it whenever you’d needed to recompute your texture.

Is there any reason why a noise texture wouldn’t do the job?
