Ever since meshing my high-detail kit layout this evening, I've been trying to export from Max 2010. The process takes unusually around 2 - 5 minutes, where it suddenly crashes Max.

Is there a poly limit for Nifskope?

I know the initial stage of the mesh was fine, until I introduced fine detailed circular indents to some of the walls which no doubt rose the poly count.

Update:

Possible issue with exporting Booleans to Nifskope if anyones interested. I've gotten around it by unticking the "Vertex Colours" option from the export window. This seems to get it fixed to a degree, but results in a messy mesh.

Anyone have any experience with Booleans cutting in polys?

You've collapsed everything to an editable poly/mesh before exporting right? It may help to reset x-form too.
