Yeah I usually just get rid of the shader rimlights in favor of adding them manually in SFM/Post

Its a projected texture light, should show better in the animation of course

I never thought of phong tint, I think that is what I have been looking for, I did try my best with cube maps, but they seem to be very fiddly

I have meant to ask for an age how you made the suit look metallic, I assume it is painted in?

I have seen some yoga on the beach where they had the ball, but this ball looked a lot prettier rendered than the beach ball in vanilla TF2, mainly because I was too lazy to edit that ball

Likewise! <3
