Quote from DefragIs there a better way to export from hammer -> max than using .dxf files? DXF is almost useless (faces inverted, each poly is a separate object unless you weld everything, which just causes the vertices to become even more erroneous in position in relation to the original .vmf geometry). Some kind of .map or .vmf import would be stellar.
What modelling program do you use?
In Max it's quite easy to get DXF imports to work properly - You just need to flip all the normals on the imported objects and then collapse them into a single mesh, and you're good to go.
