So with WW 2.0 beta, it seems that there were some errors when trying to export my VMF with the displacements.
The first thing I did was use the same scene that exported before but had errors loading in Hammer and re-exported with WW 2.0. This produced an error and looking at the Maxscript listener it seems to be something with the materials. I tried to fix it by making a new material and just placing, clicking send to displacements but that didn't fix the issue.

After that I thought it was just a problem with the previous displacements I had so I deleted it and created new displacements, edited it a bit and just exported that VMF. Again another error occurred but this time it was unknown.

Thank you for reporting. I'm looking into this now. Can you send me an Archive of the scene before you started testing the WW2 changes so I can reproduce this?
