Hello to all... I have a scene where I have animated geometry written out and I bring it back in via a file sop. The animation is just of some rocks flying up in the air flying down inside some water. I'm using a vdb from polygons on the file and I'm bringing that into the dop network as a static object with the mode set to Volume Sample and pointing to the object in the proxy volume field . The problem I run into is when the rocks collide with the fluid, the fluid collapses. I can remove the proxy volume and reset the mode to ray intersect and things will be fine....I have tried to explore on how to fix this but I can't seem to find the solution... does anyone have any ideas? I can upload the scene later if needed. flip_tests.hipnc
