Vellum Grain filecache timed out after certain frames March 21, 2024, 2:03 p.m.
Hi there, I am very new to Houdini
So I have a simulation that initally has around 1M grains, then this error message kept on showing up. I tried to reduced the amount of grains to around 750k, it still shows up
Below is the error message...I guess maybe it is to do with OpenCL neighborsearch?
Also how many grains can Vellium grain simulation normally support? I send an attachment of my substeps and everything else
Many thanks everyone
Sometimes the grains will fly off...when there is more than 750k particles like this
