Hi there. Easy minor bug this, I use a tool called Crowbar to decompile and recompile my Valve Source models, and it puts a comment line at the top of the character_reference.smd file like so:

// Created by Crowbar 0.19.0.0
version 1
nodes
0 "ValveBiped.Bip01_Pelvis" -1
1 "ValveBiped.Bip01_L_Thigh" 0
2 "ValveBiped.Bip01_L_Calf" 1

etcetera.

I have to manually delete this comment line from the smd file, otherwise IPISoft can't load in the smd file as the Target Export Model, saying it can't find the version number.

Thanks for reporting. We'll look into this. But the fix will likely go into V3 only.
