Humanoid Animations from CSGO, Left 4 Dead 2, and other newer games do not work correctly #5218

Open siobhan-saoirse opened 2 years ago

Details

When i try to use an animation from a Left 4 Dead 2 survivor model, it only moves some bones unlike the original animation. For example, when i use the animation tool on Nick, use the "idle_standing_fry_pan" animation, it does not look right.

Steps to reproduce

Spawn a ragdoll that has animations, use the easy animation tool and make sure it is from Counter-Strike: Source, Left 4 Dead or newer games. Pick an random animation from the model. It may look like this if you chose the animation. image This is what it's supposed to look like: image

This issue is also present in Source 2013 (excluding Counter-Strike: Source, with only their humanoid models) and other older source engine branches.

Decompiling the animation models may fix the problem, but it mostly results in a "too many g_numsources" error

siobhan-saoirse commented 2 years ago

This probably has something to do with the ".ani" files, it is using a newer version of the animation file that the HL2 Engine does not recognize properly, unlike newer games like Left 4 Dead and CS:GO.

It's probably because Gmod is not loading blendlayers properly for those models

siobhan-saoirse commented 2 years ago

Counter-Strike and L4D has a much more advanced blend layer system that the hl2 engine doesn't recognize

You can split the animations into multiple SMDs then include them in the .QC file iirc. Either that or multiple QCI files or w/ever it was. Pretty sure that's what I did when I had ported a large chunk of the survivor animations for use in a WOS extension. They looked p bad on the gmod rig tho since they had misplaced bones and some extra bones which stood in one place, so be mindful of that.
