Changing lighting origin?

I have these entities that can spawn wearing different TF2 hats, however certain ones like the helmets and bands won’t work because they don’t fit. I had a nice system in place to let me set the scale, per hat. Once I started scaling these hats, they turned all dark (meaning the lighting origin is in shadow, or out of map).

I think it’s because most TF2 hats are offset to fit the player, and scaling makes that offset shoot downward a whole lot more. The fact that I can’t use the football helmet or afro really makes me sad. So I ask you, is there any way to fix this? Is there a place I can request that this functionality be added, if even possible?

Maybe these are what you’re looking for:

render.SetLightingOrigin (undocumented)

Interesting, I don’t know why I didn’t check the clientside bindings.
