Hi Guys

Dynamics is seriously messed up in 2015.3 - Please download the scene and let me know your simulation times in 2015.3 compared to 11.6.3

Lightwave Scene

http://www.animatrixproductions.com/Dynamics.zip

Lightwave 11.6.3

Parts object 21,000 polygons
Shape set to mesh (The parts object falls onto the ground plane and shatters into a bunch of pieces)
Simulation Time: 1 min

Parts object 21,000 polygons
Shape set to convex pieces (The parts object falls onto the ground plane and shatters into a bunch of pieces)
Simulation Time: 12 seconds (That's almost 6x faster)

Lightwave 2015.3

Parts object 21,000 polygons
Shape set to mesh (The parts object falls onto the ground plane and shatters into a bunch of pieces)
Simulation Time: 7 min ( That's 7x slower than 11.6.3)

Parts object 21,000 polygons
Shape set to convex pieces (The parts object falls onto the ground plane and shatters into a bunch of pieces)
Simulation Time: 14 seconds (Thats almost 6x faster)

Really 1 minute to simulate in 11.6.3 and 7 min to simulate the same scene in 2015.3. Something seriously got messed up in lightwave 2015 when it comes to bullet dynamics

Can anyone here please explain why such a difference?

Thanks
Jason
