Topic: Help, Collision Problems!

OK, so I have a basic FPS rig set up in maratis, and I have made a map in blender. When I made the blender map, I used a technique that had an end result of a wall being split into several rectangles. My problem is, when my character is colliding with the map, it works fine except when I am strafing along walls. When I do that, occasionally I come to a complete stop. I think this is because of the aforementioned technique, and the rectangles are messing up collisions, but I'm not too sure about it. This has also happened before when I am falling against a wall I may suddenly land on the bottom edge instead of slipping off.
So, if someone has had this experience, or might know how to fix it, please tell me.

*And yes, I have tried merging the faces, but I can't find a good method of doing it efficiently, I either have to delete the faces and make an entirely new face to replace them. I also use "F" to create a face, but that almost never does anything for some reason.

Here are some pictures:
Problem1
^ this shows the type of technique I am using
Problem2
^ this shows the scene in maratis with the player's physics properties
Problem3
^ this also shows the scene in maratis, but with the map's physics properties.

What collision type is your map? Triangle mesh? What collision type is your character? Convex hull? Also, where was the origin of your map mesh in Blender? At the center of mass?

Some pictures would help also.

OK, I will have pictures up in a bit. My map's collision type is triangle mesh, and the character's type is capsule (I have also tried convex hull and rectangle). The map's origin is in the center of mass (I used Ctrl+Shift+Alt+C and then Origin to Geometry and reset the position)

Re: Help, Collision Problems!

do you have the same problem if you use a sphere shape for the character ?

also, check that your map doesn't have faces in double or unconnected edges.

Well, I removed all the doubles, and that didn't help, but when I switched to the sphere collision it worked perfectly [for now]
