Hello!
I have a Pflow setup that Vray ( 1.5 sp1, max x64 9 or 2008 ) does not seem to like:
In the birth event, the "subframe sampling" is on, because the particles are supposed to bounce off a collider object that is very close to the emitter object. If it's off half of them just go through the collider.
And the bad thing starts now: when the particle amount gets around 10000 (i'm not certain this is the reason though) Vray just hangs at "updating instances" for the Pflow object. Last lines in the vraylog are:
Updating object PF Source 01->Event 04
Number of particles for "PF Source 01->Event 04" is 91
Updating object PF Source 01->Event 02
Number of particles for "PF Source 01->Event 02" is 9503
Updating object PF Source 01->Event 01
Number of particles for "PF Source 01->Event 01" is 100
Preparing instances
Creating render mesh for "Plane01PF": fixed mesh
Creating render mesh for "PF Source 01->Event 04": moving mesh
Creating render mesh for "PF Source 01->Event 04": moving mesh
(END OF FILE)
3ds Max is "not responding" in task manager, and shows 25% cpu usage (a single cpu core is occupied I guess).
The funny thing is that SOMETIMES is does render. Like 1 out of 10 tries it does go past that stage.
I tried many things, but only when I turn off "subframe sampling" in the birth event the problem is gone.
I'll probably have to re-render the whole sequence with new settings and tweak the collisions again. Luckily I'm not facing a deadline this time
