Tokamak Physics Thread 5

Blitz3D Forums/Blitz3D Userlibs/Tokamak Physics Thread 5

ive stumbled into an odd problem, ive also posted it on the tokamak forum, but havent got an answer...

I did the tutorial on Static mesh posted on blitzcoder, but somehow with my own static mesh of a city, sometimes rigid bodies will go right through the static mesh...

the static mesh is around 50k polygons and the rigid bodies are boxes with an BoxInertiaTensor with the same size and mass as the rigid body

does someone have any ideas why this happens?
the rigidbodies arent going that blazing fast also.
