Collision detection with "hill" mesh model

[matrix]

Hello,

i have created a mesh with hills in "Sculptris".

First of all I dont want to use a TerrainSceneNode or
as HillMeshPlane and no third party physic library.
I choose modeling to have full controll over the
appearance of the terrain.

I use the automatic collision with TriangleSelectors.
It works on flat floors like in buildings.

But on my hills have the problem that the height
of the mesh changes, the collision works and I
"stuck" in the terrain.
I must jump every time I stuck.

I there a easy method to solve the problem?

Regards

Andy

Do you change the mesh after creating the triangle selector? IN that case you have to recreate the selector IIRC, or use one of the SVN version sof Irrlicht where this bug is fixed.
