can someone tell me which part of a qc file's sequence options can essentially blend two animations together? I have two basically reference poses and I was wondering if a line in the QC file could make a new sequence basically the midway point between two animations?

So I read https://developer.valvesoftware.com/wiki/$envmap and followed it to the letter, but any custom cubemaps I make won't show up on my model! Apparently I was able to do this like a year ago but now I can't. That's how I know the issue is with the vtf and not the vmt.
Below are my steps, please tell me if I'm missing any critical step:
1. Import 6 32x32 pngs into VTFedit as an environment map. No mipmap, no level of detail, DX1, DX1.
2. Select Clamp S and Clamp T (doesn't seem to make a difference)
3. Save as new vtf file
4. Reference file in VMT as the $envmap texture

EDIT: It turns out all I had to do was reinstall VTFedit (original was 132, upgraded to 133) and it works!

Hey! I found the solution! if I export it with a DMX format instead of SMD, I can drift the bones!

Thanks. i have here a simple example of my issue with the bones:

There's only one animation in this file, it's the jaw opening. when the jaw opening the bone controlling the jaw moves forward for visual's sake. note how the bone can move as a whole (not just rotate) in the blender file (in the dope sheet's action editor) but when exported as a prop it doesn't move forward when the jaw is open. you don't even need the materials, it's apparent that the bone can't move independent of its parent. Is there a workaround or something I can use?

Also when it comes to the looping animation lagging on the last frame, it doesn't appear that way in the hlmv, any ideas why it would lag in hammer?

I noticed there were some options in hlmv for assigning sounds to frames of animation, anyone figure out how to do that?

Thanks for the answers, I'll skip the vertex messing about for now. Do you know if there's a way to make collision boxes that follow the skeleton, like the characters?
Here's the file, if you want to dissect it and figure out why the jaw bone won't move back and forth in Source like it does in Blender: http://s000.tinyupload.com/index.php?file_id=97027959961836362411

I'm making the prop for Team Fortress 2, which isn't listed on the Hammer website as compatible with vertex animation (which $boneflexdriver depends on). But it is compatible with SFM, so is it? Also, is there a way to automatically create a collision mesh based on the bones? I saw an option like that in the HLMV but am unsure how to implement it.

Hello! I have recently become familiar with animating custom models using the blender source tools. Here are two issues I would like a little help with:

1. I have a custom prop of a log floating around. In HLMV and Blender the loop is seamless: it spins around back to its starting position. However in-game there's a noticeable lag when it hits the last frame and starts again. Is there any way to mitigate this?
2. I'm making another prop with 3 bones. One is still, the two are the top and bottom jaw, respectively. The animation looks great in Blender, but when I export it to Hammer it's like the bones have zero ability to move or shrink/grow like they did in Blender. Is this an engine limitation or is there a way to make the resizing and repositioning of bones work in source engine?

Thanks!
