Hi guys,
I'm developing a custom shader node for arnold and testing it in maya.
Currently the shading logic is working but the parameter update seems problematic.
If I start the IPR render, only the first paramter update will be rendered correctly. And after that no parameter update will be working, the IPR always render the old result.
If I disconnect the shader and then reconnect it again, the updated parameter will be rendered correctly, again then the first parameter update will work and keep failing the update afterwards.
What could be wrong about this?
Currently no mtd file is provided, does this affects?
