Question by maxmet · Sep 27, 2018 at 05:11 PM · shader float shader programming precision reaction

Shaders and RGBAFloat

Hello.

I've been trying to implement Reaction-Diffusion in a Unity shader. I have already implemented the system on shadertoy, so I expected the port to be quick - not so.

The problem seems to be related to precision (the system doesn't evolve as expected), so I tried switching the Textures and RenderTextures to RGBAFloat. But the shader only outputs black. The only change I've made was to switch the RenderTexture tags (and the texture creation script). Even a simple shader like float4 col = float4(i.uv,0,1); outputs nothing but a black screen.

I must have missed something on the setup. Any ideas?

Thanks!

P.S.: I can supply more details or the source code if it is helpful.
