art3mis Posted December 9, 2019 Share Posted December 9, 2019 If your simulation is using substeps can anyone confirm whether its necessary to also cache your source collision VDB's with substeps (ie using $FF instead of just $F) ? The cached collision VDB's then being referenced by the Static Object DOP in your DOP network. 1 Quote Link to comment Share on other sites More sharing options...
evanrudefx Posted December 12, 2019 Share Posted December 12, 2019 Yea, (if its moving) that's why it has $FF as the default. You can test it yourself. If you only cache $F and you go to the global animation options and uncheck integer frame values and a value like 0.1 and scrub through the time line in the dopnet on the non-integer frames the collision object will not move on those frames because there are no substeps when loading the cache (turn off display geometry and view the collision guide).
