Player Model - Jump Animation Glitch

I’m not sure why, but its only with a select few models this happens with (Death, Lara Croft)

Fairly sure you can’t fix that with Lua, I believe it’s how the model was rigged.
You’d have to decompile the model and fix the rig yourself, or contact the creator.

That happens because model was compiled for older gmod and is not compatible with new skeleton animations.

This is something you’ll have to take to the modelling section here http://facepunch.com/forumdisplay.php?f=40

The model will have the be recompiled including the female animations (f_anm.mdl) More information here: http://wiki.garrysmod.com/page/Player_animations
