Mesh causing frame-rate issue

Hey Unity3D gods. I’m having a very frustrating problem with a game I’m working on.

I built an early level for an RPG, and I have a section of floor in the “mine” area of the tunnel. Whenever my character has entered the collider on this mesh, it cuts the frame-rate in half! I ended up redoing the mesh, and I still have the same problem.

The mesh is separated into 3 parts. The walkable path area has 28 polys and uses a mesh collider. The other cliff sections have no collision at all. I know what you are thinking too…the rocks, mushrooms, mine support, and other props are causing the FR issue. But that is NOT the case! The mesh was causing this problem before the props were added.

I added a screen capture video for you guys to help get you a better idea. The game is NOT as laggy as the video shows. The lag was from the video capture software. Watch the frame-rate counter in the Statistics though.

Here’s the video. Thanks!

Its not any of those! It’s because of your model itself. it has over 22k vertices! Thats a lot! You need to sacrifice the quality of your model and ensure it is a much lower vert count. Also maybe you have too many particles as well. as too many particles slows things down too. Also you may have too many textures on the character, try just making a really good colour map for it. Hope it helps!
