Report id 7B5FECE7-C3A5-4E2C-85C8-8E54D4F18F9C, a model using BLP textures will crash the World Editor, regardless of texture size or aspect ratio.
This was initially tested in HD, on this model:
https://www.hiveworkshop.com/threads/baine-bloodhoof-young-alternates.339687/ from the Hive Workshop. Converting this model’s textures to DDS makes it not crash.
Seems to affect both SD and HD assets, but it was not consistently reproducible between maps, so it’s likely not as simple as just an error in parsing BLP
