Thanks for that! How exactly are you testing your code? I'm familiar enough with Python to get something done, but I'm completely unfamiliar with the Blender API. I've edited some plugin files by hand, but had to reboot Blender every time to test the changes, so I figured there must be a better way but haven't really put time into figuring it out yet. I see you've got both visual studio project files in the github repo. Do you write and start Blender from VS? How does that work?

Alright, thank you very much!

Thanks for the swift reply! That explains it then. In that case, a separate operator would probably make sense. Is this something you'd wish to implement yourself, or no plans? I'm willing to take a look, but I'm not yet familiar with the code and the differences between the two formats.

Hey dudes! I've got some general inquiries about the addon's importer capabilities. I've got a couple of character and camera animations in Source Filmmaker which I'd like to re-use in Blender. The characters I use are of my own making, so I have the DMX files with all the flexes at the ready as well as Blender files. I've exported my character's animations from SFM by right clicking my animationset and selecting Export > Animation. So far I've found that the character animations can be partially imported into Blender with some caveats. I noticed that RootTransform/Object Transform doesn't get imported (which sometimes results in jittery animations) and Facial animation is lost as well. Looking at the ascii versions of the DMX files, I do see a bone called "unnamed" that I assume to be rootTransform. Console output shows that flexes are also detected, but as bones instead of shape keys. Excerpt from the console:

Now I was wondering about the reason why these two don't seem to be supported. Is there a technical reason that prevents these features from being added, or is it simply a time issue? I've got some intermediate python experience, but I thought I'd ask for some background on this before I'd dive in to the code. Thanks for your time, as well as this very complete plugin. (loving the HWM/DMX stuff!)
