Can't Import DMX Animation from HL:Alyx S2FM

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,
PanzerDame

Source Filmmaker has a different animation format from the animations that you compile into a model for use in a normal Source game.

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

I don't know about Source 2, but for Source 1, Source Filmmaker's StudioMDL can successfully compile DMX animations from Source Filmmaker's [right-click an animation set] > "Export" > "Animation" (both ASCII and non-ASCII) and "Taunt Animation" (both Z-up and Y-up) options, and Team Fortress 2's StudioMDL can successfully compile DMX animations from the "Taunt Animation" (both Z-up and Y-up) option. (In fact, the "Taunt Animation" option was explicitly made for that very purpose!)

Zip file containing all five export types for Source 1, for use with Source Filmmaker's (or Team Fortress 2's) "player/hwm/medic.mdl" model, simply moving/stretching the left arm (and some flexes, which are skipped by StudioMDL): https://drive.google.com/file/d/1mzDdQYnXiPGf2ZXk4Cr1ZoafiH4ML6HH

(Not even Source Filmmaker's StudioMDL can compile the "Facial Animation" type - but there's still an argument to be made that it's an official DMX animation format, and as such could be supported to better integrate with official Source tools anyway. I wouldn't worry about that one, though.)

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.

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