art3mis Posted February 25, 2019 Share Posted February 25, 2019 One thing that seems to be glossed over in many tutorials is the relationship between native, non-native VDB volumes and SDFs. So an SDF can be created both ways, using native volumes via ISO Offset and aslo via VDB's using VDB from polygon. But can anyone tell me what the difference is between these 2 SDFs? ( created using ISOOffset and a SDF created using VDBfromPolygons) Quote Link to comment Share on other sites More sharing options...
toadstorm Posted February 25, 2019 Share Posted February 25, 2019 It's the same as the difference between native fog volumes and fog VDBs... VDB volumes are sparse. Voxels that are deemed "inactive" don't have data stored in them in order to save space and computation time. VDBs also have access to all the fancy VDB library of tools for smoothing, filtering, etc. Quote Link to comment Share on other sites More sharing options...
