color values are proportional on both scales

So all you need to do is take a percentage and that is what slider value you need

so, say if you have an rgb of 73, divide that as 73/255 ~= 0.29 (you can add more decimal places to be more accurate)

you can select the keyframes and then use the curve buttons to recalculate the curves from the keyframes.

As long as offset mode is turned off, moving tangents of curves should also correct the areas between the curves as well

try to bake your cloths/jiggles before the render and see if it helps. right click the model w/ the proceedural bones, and click bake proceedural bones (I think its in utilities or just in the menu itself)

you'll know you've done it when your model gets new bones added to it that control whatever it is was being generated

common issue that often has to do with people missing some important assets. In my experience,, it's usually when someone is missing a cosmetic item that is attatched to a rigged character.

What you need to do, is make sure all of your contents are synced together. Make a workshop collection of everything you guys will use

as far as I know, every map in SFM needs to have/has HDR. Must be something else causing your issue

all tf2 models will by default be in the mods tf and tf_movies (you can select them with the drop down at the top when you browse for models). All workshop content is seperate from TF2 content (in workshop folder)

yes, what ohko said.

Muzzle flash animation and particles that need to "start" at a specific time (like an explosion) should have their start time to wherever you want it (and accurately by the milisecond. if you put your playhead on it you can see what time frame it is specifically.)

moving the playhead in and out is also pretty necessary too, so do that as well and make a habit out of it

hmm, you should really look into doing SFM stuff then. Creating a render like what you have in your screenshots is very very easy in SFM (and when you do it in SFM you get advantages like custom lighting and AO).

Locking hats and attatching objects is also fairly simple and easy too.

oh, and to answer your oddity, "rig_biped_mets.py" is a python script for a character rig (Like an IK rig). Necessary for character models with non-standard bone names or constructions to have IK rig hand and foot controllers, or custom rigging scripts for better results (like rig_rev)

in my experience HLMV isn't really that useful (tho if there's some cool features in there I don't know about then that would be cool)

I haven't really used it like at all unless I wanted to make sure a model worked in a mod or game.

I think one thing you could try to do, is attempt to open the model with TF2's HLMV maybe, but as for specifics to the model itself, I don't really know. I assume if it opens up properly in SFM's model viewer, it will also open fine in HLMV

the first thing I might reccomend is updating your drivers for your video card and maybe see if there's a program on your pc using lots of your RAM (task manager can tell you this)

second, when you're making a poster, you can bypass some of the lag by making your clip really really short (like just a few frames long)

if you think too many models, one thing you can do, is find your gameinfo.txt in usermod, and unmount all your mods except the essentials, and see if it helps
