Hi there,
I was working in Maya 2023 and was following this tutorial working with the brush tool, and while it worked the first time (roughly December of 2022), it has stopped showing up in the Arnold render view, and an error shows up saying “Trying to clone a NULL object.” While trying to fix this, it appears that the brush itself would not render in Arnold, though it showed up in both the workspace and the outliner. I have also checked and made sure that both the MTOA and MASH boxes were checked in the plug-in manager, and it is still not showing up in Arnold renderview.
Is there some way I can fix this? It would help a lot. Thank you!
