legomir Posted January 12, 2016 Share Posted January 12, 2016 So i have a lot of points and i want convert it to fog volume. VDB can do this, but is really slow with a lot of points and small psale so I try use VDB from particle fluid and convert SDF to fog in viewport looks fine but still blocky in render. Why? How I can fix this? problem.hip Quote Link to comment Share on other sites More sharing options...

dpap Posted January 13, 2016 Share Posted January 13, 2016 1) use polygon sphere with high resolution so that is smooth. using a primitive causes an auto conversion that's why you get an error on the vdbfrompolygons node 2) most important :use smaller voxel size 3) use fog vdb in the vdbfrompolygons node so that you can avoid the conversion problem 1.hip Quote Link to comment Share on other sites More sharing options...
