Guys, I'm new to rendering with MaterialX and Karma. I have seams in the displacement shaders. I think I need to adjust the middle value of the texture used, but I do not know how to do it properly. What's the best strategy?

You may want to download a new build. Code improvements for displacement are in place, including eliminating or reducing visible seams.

You could use a mtlxSubtract node to offset your greyscale value by 0.5.
