Hi.
If I had a standard grey scale image (noise), how do I plug that into material X standard surface to get bump working. I have treid a few things but am unsure.
Thanks in advance! Best

A greyscale image is not the same as a Normal map, those look purply. I'm not sure if Karma supports actual bump mapping yet, but you can use a greyscale image for displacement. You have to "collect" up two shaders to combine them, and assign the collected node to your object as the material.

I don't know if you can use the old bump to normal vop within materialX (it would be KarmaCPU only, since XPU doesn't do vex), I tried it for a minute and wasn't able to.
But.. if it doesn't have to be explicitly "in" the shader network, you could go through cops and use a vopcop filter with bump_to_normal to generate the normal map from your bump. That works.

Would the mtlx height to normal be any good?
