It's prolly cuz SFM Workshop doesn't download anything sometimes.

Same thing happens to me all the time cuz of quota limit, but it fixes itself overtime or by re-launching steam and SFM.

It's working now that I've redownloaded it, but before it was saying in the console that "Model (filename)not a .MDL format file!". It's happening with a few other Honkai models too, like Silver Wing: "Model models/bronya_silver_wing/honkai_impact/rstar/bronya_silver_wing/bronya_silver_wing_sfm.mdl not a .MDL format file!"

@wiimeiser

How can it be not in mdl format, if you can only upload files that work within SFM?

It literally says in desc:
silverwolf\honkai_star_rail\rstar\silverwolf\silverwolf_sfm.mdl , and it works fine for me.

That said, it seems to work if you override the mdl file with the Gmod version. Just using the Gmod version alone causes the model to become distorted though (which appears to be due to not having a skeleton so it defaults to the ValveBiped skeleton)

Broken, reporting that it's not in mdl format and appears as an error.
