I'm just tryin to integrate bullet with my terrain, and i have small problem 
look at screen :
green terrain is from bullet ( debug draw ), his center is on 0;0,black terrain is mine ;p he had right bottom corner on 0;0
And now i have question, how to match it? :S For bullet terrain im using btRigidBody, btHeightfieldTerrainShape and btMotionState ( im getting matrix from getOpenGLMatrix(..) ) Any simple way to set offset or something like that in bullet?
Regards! x6itru.
