Description
Alongside its set of usual playermodels, TF2 includes a set of hardware morph (HWM) playermodels that use a more advanced set of facial flexes than their regular counterparts. Previously, the use of HWM models and their facial flexes could be controlled with the variables
mp_usehwmmodelsandmp_usehwmvcdsrespectively. However, at some point in TF2's lifetime, the code for these commands was commented out, forcibly disabling HWM on all PCs regardless of these variables' values.As this PR's existence likely suggests, I don't know why this change was made.
This PR uncomments the code for the commands
mp_usehwmmodelsandmp_usehwmvcds, once again allowing players to use HWM by setting their values to 1. In order to preserve the current behavior of not using HWM by default, this PR also changes both variables' default values to -1.This resolves ValveSoftware/Source-1-Games#4751.
