I realise there is a problem with scaling in DB Pro, and retrieving the scaled object sizes. But how do you get around this with NDB_NewtonCreateTreeCollision? You can't pass it a scaled object and create a "good" Body, it creates one of the original dimensions.

I imagine this might also be a problem with hulls.

With the new verison of Walaber's wrapper there is a command that lets you scale the "Newton object" too. It is explained in the last demo of the last wrapper (1.31 and maybe 1.30 too). So after you have scaled the DBPro object scale by the same amount the Newton object and that should the work...I think!
Hope I was helpful

From Walaber:

Quote: "actually yes, in the latest version there are a few un-documented commands for this:

NDB_NewtonCreateTreeCollisionWithScale

set the desired scale into temp vector 1 before calling (NDB_SetVector sx#, sy#, sz#)

also the unpotimized version

NDB_NewtonCreateTreeCollisionWithScaleUnoptimized


you can also do the same for convex hulls:

NDB_NewtonCreateConvexHullWithScale
"
