Atom 516 Report post Posted May 3 (edited) Hi All, I am playing around with the L-system gnarly tree preset and I want to convert my tree to VDB and then back to polygons for further processing. When I add the convert node, however, it does not convert the entire tree, the lower trunk is left out. What causes this? How can I get Houdini to convert all of my geometry? ap_gnarly_tree.hiplc Edited May 3 by Atom Share this post Link to post Share on other sites
MENOZ 29 Report post Posted May 3 it's because you have open surfaces, try to create a vdb from a tube with no caps, it doesn't work. you need really low res for vdb to fill holes. you need to work a bit on the tree geometry to clean it and close it. booleans might help.

Atom 516 Report post Posted May 3 Thanks, I keep forgetting about close surfaces, I'll try that. I agree, that preset is pretty yucky. That is why I was trying to POLYGON->VDB->POLYGON round trip it to clean it up a bit. Basically trying to make something to sculpt on. Share this post Link to post Share on other sites
edward 331 Report post Posted May 6 PolyFill is one of the new options in H16 to cap holes. It's worth a try. Share this post Link to post Share on other sites
