PRT Loader --> PFlow (prt birth,prt update) problem.

Hi guys,

For ex. create box, volume it by prt volume, save particles, and loaded to prt loader. ok its'done, I have a particle box , then i want to do something with this in pflow, maybe fall down, by gravity or something, so I put this loaded prt to pflow. PRT Birth operator, and PRT update operator, but when i render this out i have only part of my box. The box from prt loader has 100x100x100 but after load to pflow, pflow box has only 100x100x1. I try find the solution in maybe prt loader in visibility node, "load by first... load by every" nothing happened. I don't know what im lookin, where, maybe do some mistake.

select your pflow system go to system management tab

check your particle amount upper limit. Might be capping your amount. Turn this up.

As Nickolay suggested, PFlow has a default limit of 100,000 particles. The default Render time Spacing of PRT Volume is 1.0, so I would expect you to get 100x100x10 loaded if you did not touch anything else.

Note that opening the Krakatoa GUI automatically increases that limit for all scene PFlows to 100,000,000 (this can be turned off in the Preferences, but nobody does that).

So if that is the problem, just open the Krakatoa GUI and see if that fixes the issue.
