In my first person shooter game, there are times where the player has to wear an Iron Man - style suit. So I made a suit. I put the camera inside the helmet and it fits so well but I have a problem, the external lights leak inside. The front is obviously made of glass and of course light in the front would leak inside but my problem is the light coming from behind leaks inside as well. How do I solve it?
Yes I want the illusion to be realistic. There are times when the camera focuses into the players head inside the helmet. I went with baking the shadows you now I only use shadeless for the environment materials.
You could also try lowering the camera clipping starting range and create a overlay alpha of the helmet shape on a plane, this could help performance a bit. To make it look a bit more realistic, you could add a subtle sway movement animation on the plane using the action editor , then applying the action directions according to the player movement.
