Hi, there is a bug for the simplex3D not monochrome on macOS Intel
Thanks for the report, we’re already on this one!
I’ve tracked this down to a bug in the tools we use to convert GLSL to MSL. Awaiting a fix.
FYI for those in a jam on this, you can still get RGB noise by using Perlin functions in the Noise TOP. I know its not the same, but perhaps workable for you until we fix…
Yes I found this solution… thanks
