simulation alternative method (pyro)

[ltmedic]

Hi

 

I'm trying to make a house destruction simulation and trying to add the dust/smoke created from the destruction. Using the debris shelf tool to emit particles from the destruction and using those particles to create the pyro. The debris particles has a birth rate of 10000. 

 

The issue i'm having is that when simulating the scene it is so slow, when trying to save the cache to my hard drive it's stuck on calculating VEX for volumetric shader and has been for 30mins. i'm assuming this method is very inefficient and there is probably a faster way. Is there an alternative way to create a dust/smoke from the destruction?

 

Thanks
