Incredibly helpful. Thank you!
WOW! Thänx a lot for this great and super useful tutorial!!! So many clever and nice tricks. The one with the pscale and displacealongnormal trick is great!!! LOVE IT!!!
wow. glad i learned about the stash node from this video. thanks a lot!
Amazing!
Thank you! That’s amazing!
Thanks for sharing the workflow.
definitely learnt few new things.
Glad to hear that!
Excellent tutorial
for making objects on geo without intersections and proper aligned, it's more easy to use MOPs. Anyway, great tutorial how to combine different solvers and interact them
So pretty. I love it.
Bloom & Glare thanks so much!!
Thank Youu
Sure!!
I love deeply🖤✌🖤
Love your tutorials, really helpful! May I know do you have project file provided?
i dont think you need attribute transfer for the normals , just use normal node before the scatter and the scattered points should inherit those normals.. it doesnt matter here, but in bigger cases, the attribtransfer tends to be very slow
Great walkthrough, thanks for posting it! I'm pretty new to Houdini. Can you tell me why the VDB is used for FLIP collisions rather than the geo itself? Thanks :)
Matt Curtis thank you for the comment! Glad you enjoyed the video. It’s just the way Flip works. It takes the particle velocities, transfers them internally into a volume, solves the motion with collisions etc, and then updates the particles positions using those volumes. It’s a sort of hybrid solver. Dealing with both particles and volumes
@@K1FFVFX Good to know, thanks!
One more question... hope it's ok. Why is it better to use the solidconform+vellum tetrahedral to create actual solid geometry? Doesn't vellum configure softbody add strut constraints anyway without having to make them actual geo?
Houdini offers two options for softbodies. The strut softbody and the newer tetrahedral softbody. The tetrahedral softbody creates two types of constraints. Soft distance constraints along each tet edge to act as springs, as well as tetrahedral volume constraints to maintain volume of each tet. Where as the strut softbody creates random struts between opposite interior points of the geo which creates a rough form of volume preservation. If you drop down a strut softbody and then also drop down a tetrahedral sodtbody, and compare them, you'll find that the tetrahedral is more realistic. It actually has a volume of polygons, like organic tissue. Unlike the strut, which just has long struts going from one side of the geo to the other.
@@K1FFVFX That makes a lot of sense. I never thought of how 3D tetrahedra would make for a more accurate volume preservation than 1D struts. I'll have to remember that setup.
please hip anyone
good tutorial. just kill the music, no need for it.
