Is there any way we can access derivatives functions in karma for MaterialX at the moment or is this something that has to be supported on the MaterialX side of things? It would be incredibly useful to make screen space curvature and other useful nodes for shading.

It would be incredibly useful to have these functions if they are not yet implemented so it would be great to hear if this is something sideFX can/has implemented or if this needs to be suggested to the MaterialX team.

Best,
Rich
