This is the Famas G2. The standard weapon of a french soldier. Approximately 120 000 polygons, rendered in Cycles. Modifiers are not applied.
two questions: one, would this work for a game, and two, are textures/decals going to be visible in my game? i rly need a reply soon.
This is a high poly modelisation. So, I think that you should forget it if you want to use it in a game. Moreover the textures are done in cycles. But you can quickly make new textures for the internal renderer of blender. :) Good luck for your game !
