Boolean doesn't work after Convert VDB (polygons)

Recommended Posts

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.

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)

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...
