I'm trying to minimize the amount of work involved in my current project, which is a first-person shooter, and the first approach i'm experimenting with is to remove first-person weapon/arms models entirely, relying only on the third-person model. So far, it looks good, with the only problem being that the camera has to be placed on the character's chest, close to his neck. This can ruin the immersion, though, by creating a mismatch between the player eye-level and the camera level. Specially during combat.
I'm sure there are more studies in this area, FPSes being quite popular. Does anyone recommend any article on the subject? Maybe a GDC talk or something? Thanks in advance!
