Portal 2 Community Edition (P2CE) stores its bin files like hammer and studiomdl in "Portal 2 Community Edition\bin\win64\" and when I try to use it as an engine path it just says "Invalid Engine Path".

I'm not talking about using multiple uvs in models, I'm saying I have copies of the same mesh that has uv maps for different skins of the model and I want to export each model with a different uv map.

I have a pretty unique problem, I'm making models for Portal 2's Puzzle Maker which means that different skins of the same model need to be different models. Normally I'd just use different textures between the models and swap those in the qc but it got me wondering if there was a way to optimize the workflow and space by using the same texture. Right now I have multiple objects with linked meshes. I have different UV maps on the mesh for different "skins" where I can use the same material but different UV coordinates. How can I specify which UV map I an object to use when exporting.

TLDR: How can I export an object with a specific mesh UV Map.

I'm pretty much a self taught when it comes to blender so maybe I'm missing something. If its not currently supported by source tools is there a way I can quickly edit the addon myself to do so? Help would be appreciated.

Never mind, I updated the addon to the latest version to check if that was the problem. It didn't changed anything so I thought it was. Turns out I needed to restart blender after updating to fix it.

Whenever the Source Engine Export dropdown is expanded, this error is spammed in the blender console


I am using Blender 2.93
