Thanks so much for this, it’s a tremendous help! I had one minor issue that I’d like to point out in case it helps anyone. Some of my branches were falling off when I started the sim. The issue was with the attribute wrangle that snaps the points into place right before the fuse. Sometimes, it would try to snap a point to another point which would later be moved away, leaving the first point hanging in space. I solved this by adding a group combine before the attribute wrangle, subtracting the start points group from the level 2 group. Maybe you’d need to do all the groups in some scenarios, but all the problem points were on level 2 for me. Anyway I hope that makes sense! I love the results I got from this tutorial, and it was so quick and well-explained. Thanks very much :)
Great technique! I did also had some issues with the Attribute Wrangle node before the fuse node. I had some misspelling issues but I had to increase the fuse snap distance to over 1 and that is the only way I got it to work but it works fine. I think my tree is larger; 25 meters and maybe that had something to do with it and only created 3 branch levels beside the trunk from 0-3
I was not sure how to delete all of the leaves except one. I just deleted them by selecting one and deleting the rest but I am not sure what the connectivity node does. Second question: how is the number of leaves reduced in the for loop?
Great video, helped me a good bit. I've been having issues with branch orientation however. When a strong wind bends the tree trunk, branches roll/spin around the trunk as if it were a hinge. I've tried using various vellum constraints and had no luck; does anyone have a solution for this?
Hi Fabian, thank you very much for this tutorial, I am new in Houdini and it's been helping me a lot !!! Just stuck on snapping the start points to prev bunch. When I wrote your vex, my tree skeleton's shape deforms and loose its original shape. How can I fix it ? Thank you very much !
Hey Eyup! Thanks for your comment. When you enable the wrangle to snap your start points to the prev_level, are they snapping or the wrangle doesn''t do anything for your? If they snap, it should work after you fused the points on the next node.
Thank you for this awesome video! The one thing I keep having trouble with is the moment I apply any gravity or wind to VELLUM_TREE_SOLVER, everything breaks, The tree just doesn't hold together.,

Thank you for the VEX snippet for snapping start pins! Was lost without this on my own project
Extremely helpful tips/guide! Thanks heaps for making this Fabian!

Thank you for this tutorial. I have been searching for a way to animate Houdini generated trees. This tutorial is well done and easy to follow.
Thanks a lot James! Glad to hear that 😊👍
this was a great tutorial, thanks a lot!
Now I see this and It's damn cool! Thanks man
Thanks!
Hi, is it possible to get the hip file for the project? Having some trouble with the nodes
I was not sure how to delete all of the leaves except one. I just deleted them by selecting one and deleting the rest but I am not sure what the connectivity node does. Second question: how is the number of leaves reduced in the for loop?
Hi hi! Everything works well for me until I do the vellum sim on the leaves. They just jitter like crazy even without any force
Great video, helped me a good bit. I've been having issues with branch orientation however.
When a strong wind bends the tree trunk, branches roll/spin around the trunk as if it were a hinge. I've tried using various vellum constraints and had no luck; does anyone have a solution for this?
This is great man! Unfortunately the pointdeform does not work properly for me. Any advice on how to solve the problem?
Maybe playing around with the radius on the point deform will help. I would try to feed the upscale of the skeleton mesh onto it

@@FabianStrube Its snapping but in a bad way. Shape becomes like "connect the dot" puzzle game :) and fuse is not fixing it.
Thank you for your great support Fabian, wrong written VEX (one wrong written semicolon :)) caused the problem but now its all OK.
Thank you for this awesome video! The one thing I keep having trouble with is the moment I apply any gravity or wind to VELLUM_TREE_SOLVER, everything breaks, The tree just doesn't hold together.,
Sounds like the points are no fused together correctly. Do single branches just fall of?
@@FabianStrube Ya! Thank you for pointing me in the right direction :) Will take a closer look at the Fuse node.
