Okay I found out that if the username or machine string contains an ó letter it fails the import. I deliberately removed those from these dmxes and now it seems to import properly.
Still, to replicate the issue just put an ó letter in the user or machine string.

Now it actually imports just fine in all versions, even Blender 3.1 and 3.2

Hello!
We'd like to use BST to help create our upcoming Dota 2 Short Film Contest entry.
Currently there seems to be an error whenever we're importing an animation .dmx that was exported using Source 2 Filmmaker.


Files in question (test files): https://dl.dropboxusercontent.com/s/ydzor3810679fl0/DotaAnimDmxes.zip

I've done some tests and these are the results:
this error occour in:
Blender 3.0+ and BST 3.1.1+
this error did not occour in:
Blender 2.92 and BST 3.1.1

We'd really like to use the latest version of Blender in order to better the team's preformance and results so I hope this can be looked into, thank you in advance!

Sounds typical, but make sure the folder exists that the model is complied to.

S1FM at this point is pmuch forgotten, I'm also not sure if they even readed my bug report. Hard to tell because some people claim they only read reddit, but posting this 'bug' here would get downvoted to hell. I also sent them a mail to the SFM team / Dota 2 Dev forum, I can only pray this gets fixed soon.

Yea It seems like it. Thank you for your input. I just hope they add more of the S1FM features and dmxedit features + fix this issue. S2FM seems really promising, but It's not continously updated nowdays.

Lately I've been trying to make the Stereo controllers work in the Dota 2 workshop tools as an experiement ( Source 2 ). Besides that there is no official support for Wrinklemaps / eye controllers (or dmxedit in general), there is the functionality for stereo flexes / correctives / control groups.

I couldn't find any documentation about the "Morph Target Weights"[i.imgur.com] either.

( COMBO() is the corrective shapes, NWAY() seems to take care of the _multi shapes, but no information about 2WAY_0, or 2WAY_1, these are generally not documented at all? )

So I tried to export the model from Blender with Advanced Flex Properties
( Controller source: saxton_head_stereotest_controller.dmx )

However it seems the left_ side of the controller doesn't work. I want to belive this is an error with the Engine itself, I'd still like to report it here just in case it is an issue with the export.

Illustration of the issue.[i.imgur.com]

Source 2 seems to build these morph rules automatically, there is no issue with the HWM face functionality (Correctives are working really well!), only the Stereo control seems to not work. I haven't found any Dota 2 models with Stereo controls so I couldn't give any reference from the game itself.

The DMX files I used[sta.sh] (Exported with latest Dota 2 binaries: D:\Steam\SteamApps\common\dota 2 beta\game\bin\win64\)

Any help in this matter would be heavily appriciated, either if It's an engine error, or the way I complied the model I really want to find a way to make this work, because creating left_ right_ flexes for each shape manually would be very tedious.
