Blender uses metres, Source (mostly) uses inches. If you have a model made in Blender you will need to scale it up.

Hi, the Source Tools should never be able to crash Blender. When the path changes the script will check for the presence of resource compilers, which should be a simple and safe operation.

Please report this as a Blender bug and they will ask you for the technical details. I can't make it crash myself.

You don't have the latest version, this was fixed in 3.1.1.

Please upload the files you are importing somewhere, including the QC.

The error is related to QC import, so you should still be able to import the various model files manually.

You probably just needed to restart Blender. Don't worry though, I'd always prefer that people report errors that they see. :)

Oh boy, things get confusingif you want to use an older DMX with single underscores in modeldoc. Why did you do this, Valve?!

I'm getting a Traceback error, I apologize if that's too vague.

That is too vague. Please take a screenshot of the error.

I mean is this the Source 2 filmmaker, or the original one?

What happens if you import the same file into Blender?

Unfortunately no, that would only tell me what the author of the third-party decompiler knows. What I'm really interested in seeing is whether version 23 of the DMX model format exists and is supported by the engine.

It looks like I'll just have to add double underscore as a manual setting in the exporter.

Thanks for this information. It's hard for me to support this version of the engine as I have no VR hardware, which makes buying Half-Life: Alyx a bit pointless.

Unfortunately the "biped_standard_model" sample DMX files that I have from the Alyx SDK are version 22, which is the same as for earlier Source 2 versions (which use a single underscore). That makes it hard to differentiate between the two.

Does anyone know of a sample DMX file for this build of the engine which includes flexes?
