Please let me know if you need anything else.

Sorry for late reply. (Initial posting is close to my sleep time)
Thank you for you two gentlemen (or ladies) help.

I just remembered that the Taunt Animation menu in S2FM shown StudioMDL is missing, and the StudioMDL is nowhere be found in the entire Half-Life: Alyx folder. I believe this might be the cause that my pose DMX cannot be import into Blender.

i am using the Source 1 Filmmaker for now, as my previous posing does work in Blender from there. Would have to return to type those QC for my custom model, but this seems the only choice for now.

However, this is a DMX parsing error, and that at least should work. Please upload the DMX file you are trying to import.

Do you still need my DMX file? Should I sent it via DM?
I can send you along with my model DMX as well.

Hello:

I made a pose as an animation from Source 2 Filmmaker in HL:Alyx, and export the DMX file as either "Animation" or "Taunt Animation".

When I try to import the DMX to my model in Blender, it failed to apply on my model and this show up at console:

The above exception was the direct cause of the following exception:

I do not know what this message meaning.
Should I do the pose at Source 1 Filmmaker instead?

Thanks,
