Hi,

I'm getting this really really weird crash when I plug in the MTLX Standard Surface to the Output for a Karma Material. My material is super large, it contains a ton of nodes that are building dynamic masks based on primvars in Solaris and all connected to the MTLX Standard Surface. Karma renderer is OFF when it crashes when I connect it to the output.

What is even more weird is when I take a portion 1/4 of my node setup in the Karma Material and hook it upto the same MTLX Standard Surface to the output, it's fine! No crash. And I slowly build it up, adding all my other nodes to the same MTLX Standard Surface, it has a higher chance of working! In comparison to when I connect all the nodes with Karma Renderer OFF to the same MTLX Standard Surface to the output, it 100% crashes, without log and without warning.

Can someone shed some insight on this?
