use local scaling on convex hull makes simulation explode

[pico]

Hi Erwin,

for the last Bullet version it was needed to set the local scaling on convexHulls BEFORE adding points.
This doesn't work anymore. In fact whenever using a a local scale different to 1.0,1.0,1.0 the simulation will explode. It doesn't matter if the scale is set before or after adding points. Such object will sink into static geometry and bounce around without any force applied to them.

Maybe this bug was introduced with trunk update 1370 "Copy the cached local AABB for ConvexHullShape instead of recomputing it." from October 8?
Our last update was on October 22.

Thanks

There was some recent work going on to try to re-use GJK/EPA implementation between regular and Cell SPU optimized version. While making things non-virtual it broke the scaling.

It has been fixed now.

Thanks for the report!
Erwin
