alex333d Posted August 18, 2017 Share Posted August 18, 2017 (edited) Hello. I have some problem with boolean SOP, when I Shatter model after Convert VDB to polygons, it just slices geo. Doesn't make separated pieces of geo. I tried to remesh and fuse geo before Shatter but it gives me nothing. boolean.hip Edited August 18, 2017 by alex333d Quote Link to comment Share on other sites More sharing options...
Noobini Posted August 18, 2017 Share Posted August 18, 2017 it's same problem as this: basically, the Prim Normals aren't consistent and that confuses Boolean...haven't found a solution to your setup yet but I'm quite sure the Prim Normals have to be 'unified' first...(if you put Reverse after your convertVDB and quickly flip flop it, you'd see there's some potential clues around the ears) 1 Quote Link to comment Share on other sites More sharing options...
Noobini Posted August 18, 2017 Share Posted August 18, 2017 here's a workaround (not convinced with this method tho)...btw, in your Boolean, the cutters should be treated as surface IMO, not solid VDB_boolean_workaround.hipnc 1 Quote Link to comment Share on other sites More sharing options...
Noobini Posted August 19, 2017 Share Posted August 19, 2017 (edited) here's a workaround using VDB (not volume)...you lose a bit of fidelity...I don't know enough about VDB 'reshaping' to regain its orig shape...others might... (no I'm not 'intelligently' solving this problem...just brute force) hmm..just noticed it has a 'shell' effect...interesting...
