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?
Sorry for my bad English, I grew up in Germany.
Fake it. Make the helmet shadeless and bake the lighting.
Why you need to have the camera inside the helmet at all?
A typical setup is to have an overlay scene that shows the inside of the helmet, glasses, telescope. This way such things do not interact with the level.
I needed the camera to be inside the helmet for realism. I should just fake the lighting for now.
Hans go with both suggestions from sdfgeoff and Monster, the baked lighting will give a fps boost and the overlay scene gives more control and easier editing.
It is a game … 100% illusion
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.
Two ways I think about:
A) let the helmet cast shadows.
B) use a shadeless helmet (inside)
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.
