Hi Randall,
I’m able to reproduce the crash with this particular file, but I’ve not been able to reproduce this from scratch.
I’m using 3Ds Max 2013 with PXL DCC Plugin for 3.3.2.
I was able to take your mesh, skin it, and add a new painted cloth material exported as APB instead of APX with no issue.
There may be some corruption with the APX file that is causing the issue, but I cannot test since it will only crash.
Can you try exporting the scene as a apb?
You can see my entire process with the DCC plugin in Max here: [TUTORIALS] Photons Be Free: Mini-tutorials and other curiosities - Community & Industry Discussion - Epic Developer Community Forums
Let me know.
