For Official HD Pack by Gearbox to be consistent with HL1 expansions HD Pack.
This simply fixes the Security Guard's moving mouth with the model seen in the expansions. This is for HL1 only since the expansions don't have this problem.
I also made the Ambient.Impact Barney model work with Decay animations and compatible with Echoes.
Thank you for this fix! Finally someone made it :D
I've never noticed that thanks!
