Shader texture changing problem

[PichouPichou]

Ok I managed to find out what was going on.

I noticed that due to a security I had in my code, I wasn’t updating the texture on every onApply but only on the first call.

And indeed in that case, the texture used by the PostProcess is not the correct one but the texture used in the ShaderMaterial instead as you can see in this playground.

Setting the texture on every onApply fixed my issue of course. But it’s a bit counterintuitive to have to set all the shader values on every call.

Thanks

For the post processes you need to do it manually because there’s not a material (as for the ShaderMaterial case) that is doing it for you on your back

Ok, I understand. This is how shaders actually work
