Simplex 2D Noise based on adds Simple Noise to image.
They should have a PSA about this...
It is because this effect does not have a webgpu version and the new default for C3 is to use webgpu instead of webgl (switch back to webgl in advanced project settings). I am not sure why they do this, the current webgpu implementation has varying up/down performance vs webgl.
Thanks. Would this support webgpu one day?
Probably, once webgpu becomes better overall in performance to webgl2 in C3.
