Hi!
It seems the Curvature VOP is not currently supported under Karma, it returns shading artifacts. I have already sent a RFE, but just wanted to check if any of you have any hint about this being implemented any time soon, just like Dirt Mask, Rounded Corners shader and the limited version of trace() were recently included.
Thanks!

If anyone is still wondering, it seems the curvature VOP is still broken in karma, H19
which build are you talking about?
from journals it seems that it should already work at least partially
Houdini 19.0.469
Add basic support for getderiv to Karma. This version does not have special logic to handle smooth derivatives on a non-subdivided mesh. As a direct result, the Curvature VOP can now be used in Karma.

I cannot get the curvature node to work in Karma with MaterialX.
That's because it's not a materialX node. Only nodes that start with mtlx and a few others can be used in a materialX network. They cannot be mixed with VEX based nodes (nodes that generate code) such as the curvature vop.
Creating a karma materialx subnet before starting can help you use the correct nodes as it restricts the available nodes to just those allowed.
