I noticed one small thing that might help with rendering the UVs. If you drop the timeshift and UV texture down, so it's after the "setseed_adjust_pscale" point wrangle, the UV textures will be set to the positions of all the upressed duplicated points, not just the initial grain positions.

[@resilientpicture]

Oh yes, that's true, thanks for the tip. Much appreciated. I'll bear this in mind for next time.

Awesome thanks

Why did you make the voronoi class attribute?

[@resilientpicture]

When I originally tried out this I made voronoi class to delete adjacent points based on color difference, At the end never used it. So, yes, you can ignore that part. :)

Hey, the tutorial easy too amazing and easy to understand. I did and everything worked fine and when I exported it as top alembic and imported it in c4d to render in octane I can only see the out puller in the render view can't see those grains. Can you plzzzz plzzzzz help me out with this?

[@resilientpicture]

Thanks for your kind comments. I've never imported grains in c4d, infact I only used c4d lite for a little project. I unfortunately can't help you with this. Sorry about that.

@@resilientpicture ohh okk no worries :)

Cool, thanks for understanding

[@DiffuseFX]

Nice tutorial! Just a quick heads up - the inspiration you credit to cgrecord is actually my work... (I didn't even know it was reposted there!)

[@resilientpicture]

Thank you. sorry about that, I saw it on cg record, hence I credited them. Nice work. Updated the links to include yours. :) Subbed to your channel. 🙂

[@DiffuseFX]

@@resilientpicture No worries - thanks for the link! I could be mistaken, but I think cgrecord is exclusively an aggregator? Anyway - I enjoyed your workflow, and it's actually a little different from mine, which is always fun to see :)

[@resilientpicture]

@@DiffuseFX thank you for watching. Much appreciated.

Hello, I'm having a problem: my grains do break apart when they are stretched apart, but they always 'bounce' back together right after. I'm wondering if it is due to some setting from source-> vellumconstraints1. No matter what I have tried it always resumes it's initial shape... :( Maybe someone can help me? Here is a video to visualize the problem: i.gyazo.com/35d91bdfa7fe874895d397bf8f90d4a2.gif

[@resilientpicture]

I see the problem, this suggests that the attraction weight is too high or there is not breaking constraint in the sim. Can you please go through the tutorial again just to see if you missed any points.

[@aaponikkola1119]

@@resilientpicture Thanks for your reply. I did as you suggested and started from the beginning. I'm now at 09:55 and the grains break apart as they should! Unfortunately I cannot pinpoint what caused the issue I had at the first time.. Probably some silly mistake since I'm not that experienced with Houdini yet. Anyway, thank you so much for this great tutorial!!

[@resilientpicture]

You are welcome & I'm glad it worked out for you. 🙂

@@resilientpicture Hey. I had the same problem. ''My grains do break apart when they are stretched apart, but they always 'bounce' back together right after.'' I changed the @breakthreshold from 2000 to 200 and now it breaks the same way as in tutorial. This is my first houdini tutorial so i have no idea what i'm doing haha.

[@resilientpicture]

Lol, I'm glad you worked it out. You'll get better in the long run. Good luck.
