If it is packed object, try changing @pivot = @P, in SOP level before sending it to DOP.

Check your flame height under Combustion > Flame > Flame Height (Default is 3), if you lower it too much it tends to cause banding. Hope it helps.

Hey sunny I have gone through your file, there are couple of things you should change. 1. you should not cluster your fractured object if you want to use bullet with convex hull, if you set display your collision object on dops you will see your convex hull is inter-penetrating. ( you can cluster constraint and use glue to bind them) so turn off cluster in voronoi fracture. 2. In your sop solver you were transferring active attribute so as soon as the object goes out of search radius they change back to active == 0. instead use attribute copy in sop solver and copy your active attribute. Hope this clarifies.

if you are using python eg. you want to set expression in tx of point node my_node = hou.node('/obj/geo1/point1') my_tx = my_node.parm('tx') my_tx.deleteAllKeyframes() # to delete any existing expression my_tx.setExpression ('$TX + rand($PT)')

looks like your surface field is broken, 1. Turn on surface under Guide in whitewater object. ( inside dop) 2. Notice if its matching your water simulation, most likely it will not match. 3. If its not matching, check how did you cached your sim, you should be using DOP I/O instead of dop import. middle click on your cache node to make sure you are saving surface and vel volumes. 4. once you get your surface field matches with your sim things should work out. Hope this helps All the best.
