Ich hab mich mal just for fun im Thread rumgegraben und was gefunden.
As for changing Rochelle's name, go under resource in pak01_dir and find l4d360ui_english. Ctrl+F to Rochelle to find these two lines:
Code:
"L4D360UI_Producer" "Rochelle"
"L4D360UI_Loading_As_Rochelle" "as Rochelle"
And replace them with:
Code:
"L4D360UI_Producer" "Keith"
"L4D360UI_Loading_As_Rochelle" "as Keith"
If you want to be real thorough, replace
Code:
"L4D360UI_Multiplayer_Spray_Rochelle" "Rochelle"
with
Code:
"L4D360UI_Multiplayer_Spray_Rochelle" "Keith"
Then go under materials/vgui/logos and find spray_stencil_rochelle_01.vtf, then replace that with a stencil of Keith.
I'm going to assume, since you have your model in there, you understand about changing the objects in the VPK and won't worry about that.
Good luck, and I hope a miracle happens and you find a well-suited VA whose willing to do all those lines.
