PhysX vehicles drive/fly through static objects attached to one another with attachTo command.
Flying vehicles also take damage, but still fly through
Static objects placed in the editor so that they overlap do not behave like this
Correction is not related to overlapping as I tried attaching an object further away so that they were 10 meters apart and still could drive through the attached to object. {F25007}
Mission included
Also
place 2 VR obstacle 20x10x8 objects and name them o1 and o2
on either inits place:
o2 attachto [o1, [0,10,0]];
create player controlled vehicle on the side of the o1 block a bit above its northern side (this is where the other block will be attached to) and hit preview
Experience dimensional distortion while driving through the attached block.
Also this did work one or two versions ago while testing out large rising platform. I had created a 150x150x150 block that was animated to rise few hundred meters and attached multiple duplicated boxes to it and the flew around it and poked it around.
