Atom 639 Report post Posted May 3, 2017 (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, 2017 by Atom Share this post Link to post Share on other sites
MENOZ 30 Report post Posted May 3, 2017 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 639 Report post Posted May 3, 2017 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
