Empty collection and MOPP parser #11

Open AnyResO opened 3 months ago

I'm trying to import an old map made for Unreal Engine 2 / 2.5 in UnrealEd.

@crapola Do you know why importing the following map in Blender 4.0 results in an empty collection with no meshes?

Ah it seems your regex here expects classes to be only Brush while it could be Engine.Brush

Indeed, I think using r"""(Begin Actor Class=(?:Engine.)?Brush .*?End Actor)""" will work.

It seems that a .t3d can also be tied to a binary .mopp. Do you by any chance have any clues on how to extract the terrain geometry from this file?

I found this wiki that describes the format in more detail, but that's all for now https://github.com/niftools/nifxml/wiki/Havok-MOPP-Data-format
