I'm making a slight edit/recolour of a concrete wall texture, which needs to match the original texture exactly. When I import the edited .tga file in VTFEdit, it adds a very slight green tint to it. Normally this would be fine, but in game, obviously it's easy to spot the difference against the original concrete texture. I tried to offset the problem by reducing the green levels in the .tga file but couldn't get it matching. Any ideas? Maybe some settings with the import are off.
