Good to know, Frost. Thanks for the info.

The problem is caused by a bad file naming scheme in Crowbar. For that npc model, Crowbar writes the body mesh SMD file first, then overwrites it with the head mesh data. I have fixed the problem for next release.

In the meantime, you could try an older version of Crowbar (not sure which one, though) to get the body mesh SMD file.

I apologize for the inconvenience.

I have confirmed that Crowbar extracts only a head mesh for all 3 models contained in the mentioned addon. I will research further as soon as I can.

Oh wow. I just figured it out. When decompiling, you need to checkmark the option "Include $definebone lines (typical for viewmodels)". Although that option messes up a lot of world models, the spitter model seems to need it.

I have looked into this issue and am currently unable to figure out why Crowbar is decompiling the model incorrectly.

I did notice that the spitter files from the L4D2 Starter_Kits seem to compile correctly. Try using those instead of decompiled files.

Thank you for the model files. I will research this as soon as I can.

First, Crowbar can not unpack from a *_dir.vpk package, so use GCFScape for unpacking. That's my fault for not having an error message to explain that nothing was actually unpacked. I'll be adding the feature to unpack from *_dir.vpk files in a later release.

Second, I just tried the steps you took (but using GCFScape for step 1) and decompiled the model successfully without the error message. Again, it seems I need to fix the error message so it explains the file does not exist when trying to decompile.

By looking at the source code for studiomdl, the error seems to occur when there is a mismatch between number of meshes or bodygroups for reference mesh and the LOD meshes. Try taking out the LOD lines from the QC file and see if that removes the error. Not sure what else to try.
