well the snarky comment would be "be careful".
But really you just gotta make sure that all the transforms of all the objects and bones are applied, so that there isn't any hidden scale or location change lingering anywhere.

If the bones you exported on were just posed, rather than a rest pose, it'll break.
if the model object was scaled and not had its scales applied, it'll turn noodle-limbed.

I want to create a custom model for Half Life 2 - how do I do it correctly to avoid model errors? Every time I encountered a model stretched in different directions, either in animations or in the game, the character looked like a sandman. This happens even on original Valve models.

thanks man.
i'm already working on another guide again.

hiiii, just want to say that you're a really talented mod creator and love all the fixes your mods make to the game. Keep up the good work!

I'd prefer you did L2D0 instead, we need a prequel

Oh boy, if i had access to the source code of L4D2, i would upgrade it to the Source2013, add all my fixed props and recompile every single map with better lighting.

Unfortunately, being the guy who fixes all the assets and makes most of the guides is not enough credibility to even get onto the TLS team. So there's no chance in hell i'll ever be able to do anything worthwile...
