Replacing the Pulse Rifle in Half Life 2 creates a weird animation bug when firing.

Note that this is only when firing, no other animations cause this to happen
The animations also work fine in HLMV: https://youtu.be/esC6CKmMS-Y

Can anyone help me fix this?

What’s contained in the .qc?

Try getting rid of autoplay in the VentPoses sequence

Thank you, that fixed it!
