Hi All.

Im sure the odd shading errors you get trying to use height maps in the standard surface worked when I used to change the input RGB greyscale height map to vector3. Nothing is working now. The normal go crazy. Is there any other work around to get heightmaps to work?

You do have a dotted connector indicating all might not be right. Those can be confusing, because sometimes it doesn't matter, in this case, the HeightToNormal node expects a float and is not auto-converting your RGB vector3. Try extracting only a single channel from your grayscale RGB image. Supply only the RED channel to the converter's input.

Hi.

That also gave me errors. I think I have just fixed it using this setup. Thanks for the help though!

Maybe this will help somebody. Use the "mtlx bump" node instead of height to normal.
You can add a normal map there too.
That did it for me, Cheers.
