juncho Posted November 25, 2020 Share Posted November 25, 2020 I'm creating a white phosphorus shell explosion effect for my demo reel. Similar to what SideFX showed us in 18.5 sneak peek video. One of the challenges I have is ..there are two pyro sources. One requires many substeps since it's moving fast ( the source itself) and other one does not. So I tried this. I made two separate DOPs, one with many substeps (fast moving particles) and the other with no substep (source does not move fast) Is this a bad approach in aspect of disk and computation efficiency? Should I combine them into one single DOP and use two pyro solvers? is there any better method dealing with this? Thank you in advance Quote Link to comment Share on other sites More sharing options...
Atom Posted November 25, 2020 Share Posted November 25, 2020 (edited) One way to avoid substeps with fast moving sources is to create a trail and submit the trail, along with the lead, as the source. This can help fill in the gaps. Edited November 25, 2020 by Atom 1 Quote Link to comment Share on other sites More sharing options...
