UV Mapping on Portal 1 maps is broken

Describe the bug UVs for Portal 1 maps import in a very broken state, being way too large (100-500x too big), and misaligned between surfaces

To Reproduce Steps to reproduce the behavior:

1. Export a Portal 1 BSP using BSPSource (testchmb_a_00.bsp) in this case, using “original/split faces” option to avoid geometry holes
2. Import using this addon (UV mapping is wrong regardless of scale setting)
3. See error once you apply textures to the materials in blender

Expected behavior UVs should match what is seen in-engine

Haha was just about to write, I figured that it is that option thats breaking things. I was using it because that option + the old version of your addon caused a lot of issues with the imported geometry (I need the geo to follow sealed world rules as closely as possible). However this version seems to work perfectly with “brushes and planes”, so problem solved! Thanks for the assistance 😃

[lasa01]

Tried this myself and seems like using “original/split faces” option causes issues. I’m not having any issues with the default “brushes and planes” option. Could be that the other options create vmfs that don’t work with my current import algorithm. I could look into if it would be possible to support the other options too sometime, but this would be a very low priority issue since I haven’t heard of anyone else having any issues with using the default options of bspsource.
