art3mis Posted October 31, 2019 Share Posted October 31, 2019 Quick question about 'strobing' or stairstepping when sourcing smoke. Is the best solution to simply increase your substeps when you sim, or should this be corrected some how at the source? In my case am using a Fluid Source applied to an open ended tube.

evanrudefx Posted October 31, 2019 Share Posted October 31, 2019 I wind up doing a bit of both, but having a good source is important. I like using the trail sop to duplicate my geometry multiple times before sourcing. Quote Link to comment Share on other sites More sharing options...
rayman Posted October 31, 2019 Share Posted October 31, 2019 (edited) Make sure that geometry can be interpolated - just put a TimeBlend SOP + PointVelocitySOP before the source and turn on Velocity Blur option on VolumeRasterizeAttribute SOP, add some more Blur Samples and you are ready to go - no need to trail it or use more solving substeps. Edit : Just realized you are using the old fluid source - there should be alternative Velocity Blur option , but keep in mind that it is SLOW.
