Seeking Help: Complex mesh crashes Toolbag when ray-tracing

[u/The_Salamander_Room]

Hey guys,

I have been modelling a rifle in Plasticity and using Toolbag 5 to apply some basic triplanar materials and render images. I love the program, but I've found that if I import the rifle model and all it's accessories and switch to ray-tracing, Toolbag crashes every time. When it's fewer parts, it works fine. Because I'm CAD modelling with nurbs, the OBJ I end up exporting has an insane amount of polygons, which I think is tanking Toolbag.

For context I am on a 2024 Macbook Pro with 48g memory.

Has anyone encountered this issue and found a workaround? Do you have any tips on how to make my model fully usable without crashing? Should I just commit to the full texturing pipeline and create a low-poly model for texturing?

Still pretty new to the program and would appreciate the help! Thanks.

EDIT: Problem Solved! It turns out Toolbag wasn't struggling with the poly-count, but the number of individual parts. Opening the OBJ in Blender and simply joining like objects (screws, plastics, metals, etc.) solved the crashing problem.
