I'm trying to create a 3D-Walkthrough, but there occured a serious problem. I've created a model in 3d-Studio, imported it in Unity, added a Box Collider and a Player Object. Everything works fine, but sometimes when the player comes near the walls I can look through the walls what's behind them... I can't walk through the walls - that works fine. Anyone got a solution?
Your camera's near clipping plane is probably outside your character collider. Try moving your camera closer to the center or to the back of your collider, or make your collider bigger, or reduce your cameras near clipping plane.
