DTS Import?

#1 In a manner of speaking, Yes, you will get a mesh and rig, but any animations are corrupted. That pipeline consists of utilizing your license for Ulitimate Unwrapped3d and pushing the shape to Milkshape. It's not pretty and not always successful, depending on the DTS version you've got the shape in. The farther back, pre-SDK DTSPlus!, the worse the process works....I don't believe the author is using the DTSPlus! SDK to produce his DTS processor, and the results are quite mixed. You can try to find the Source files and push those to Milkshape, I know that there is a Max exporter that I've used with fairly good results, except it's written with old Max values for Milkshape, that have since been expanded to be quite high, 65,000 Tris, etc...longer named strings, comments for objects, etc. Good luck.

The ShowToolPro[fairly inexpensive], will expose much the same data, while maintaining the authors' rights, as a Source decompile would not.

There is a default skeletal rig included with the DTSPlus! exporter documentation, that is quite useful for loading/MODDING your mesh onto the SDK files.
