Thankfully, a friend sent me the files I needed, in hopes that'd fix my issue and it did. I was really worried I'd be stuck unable to do anything. I do appreciate the offering of help in here though!!

Messaggio originale di Artfunkel:

Which part is missing, exactly? Here's how it should look: https://developer.valvesoftware.com/w/images/8/80/BST-sceneconfig.jpg

When I first started doing these ports, it looked like this:
https://media.discordapp.net/attachments/715667789230374993/778343513079283732/unknown.png

and now the Forward Parity tab down is missing. I'm not even able to apply any cloth physics. I'm not sure if I'm missing anything at all, or if I've messed something up after I moved to my new computer

Sorry if this is something that's been debunked before. I port models into source 2 for commissions & just general artwork (HL:A's source 2) And I recently got a new PC and I've opened Blender today to do my usual port of models, and I've lost the segment that usually sits just under "Weight link Cull Threshold"

Where I would usually select -y and then apply the cloth physics. But those 2 options aren't there.
I've set the DMX version to Binary 9 model 22 like I have been doing for the past few months, but I'm not sure what's going on and I would appreciate any help!
