Custom mesh crash

I’ve just tried adding a custom mesh to an item in my mod and it all works fine in the ADK and on my server but for some people it crashed their server and wouldn’t start at all.

I found the mesh on a free mesh site (can’t remember which one) and imported the .obj file and textures into the ADK do I need to do anything else?

Any ideas what the issue could be with it?

the polygon count could be too high. Hence people with low tier pc may find it crashing when running out of memory. Check the polygon count in adk and if its too high, u should reduce the mesh in your modeller
