Post a picture of how you have BleST set up in Blender.

Have you applied the Transforms?

Also you haven't told BleST what game and version of StudioMDL you're exporting for.

Where's the QC? Do you have $staticprop in it? if yes, delete that command and recompile.

Blender main menu, Window - Toggle System Console

The Nem's Tools website disappeared, not sure when, but there are other locations where you can find the contents that were on the site.

This link to game banana has all the tools in a convenient RAR file. I've download this and scanned it thoroughly and found no bugs in it...

I would, but I haven't made it yet for Blender 2.8x

Oh, SOB, that would be simple!! Never even thought of doing that.

You need 2 add-ons for this. Cat's Blender Tool (to import the MMD PMD/PMX/VVD files) and Blender Source Tools (to export the model as DMX or SMD/VTA files for compile to GMod) and a lot of work in between.

Good luck with that. I've been searching for a function to do that since forever.

Just tried BleST (3.1.0 master from the GitHub) in Blender 2.90(alpha). I loaded my 2.83 settings on startup to transfer then to 2.90a. Imported a couple of models of various types, Exported and compiled. Things seem to be working ok. Have to test animations yet. but getting models into and exporting from Blender 2.90 seem to be alright using the current master from the GitHub.

I haven't tried the current BleST stable (3.0.3) though.
