WoweeCollision previously only contained terrain triangles; placed WMO buildings had no collision in the exported zone, so players could walk through walls. Added WoweeCollisionBuilder::addMesh() that transforms a local-space mesh into world space with slope-based walkability flags, and the editor's exportZone now walks every placed WMO and feeds each group's geometry through it. Indoor vs outdoor groups are tagged via the WMO group flag.
