Hello - Is there a way to show motion paths at the sop level?
I see you can do at OBJ level - https://www.sidefx.com/docs/houdini/basics/motionpath.html [www.sidefx.com]
but would be really good to be able to do the same on a sop level animation geometery

Hello - If you use Octane then i can really reccomend the OD Tools Octane 'QuickSetup 2021'
https://vimeo.com/380742237 [vimeo.com]
https://origamidigital.com/cart/index.php?route=product/product&product_id=66 [origamidigital.com]
That said, you can create the Octane Render Target in a 'Matnet' or 'shopnet' within SOPS i think many of the tutorials a quite old.
It's ages since ive used displacement but i think you pipe in a DISPLACMENT node to the displacement slot on root material and then your texture into that displacement node. It's then a case of playing with the heights on the dispacement node
I know Rohan Dalvi has a few tutorial on his YouTube
https://www.youtube.com/channel/UCfGN9OlJF9KakdyUK04M3cA [www.youtube.com]
And Entagma have used it on some of their tutorial too, although none spacifially about Octane, more using it as the render engine as part of another tutorial.

Very interesting - So as a grand master of VEX etc... how does it look? Sorry you'll have to excuse my ignorance on the GPT-3 deep/machine learning stuff, but did it give you fully working code with comments out the box?

Houdini Indie and Apprentice » Nails not falling correctly

Hello - Just having a little play with this (only got apprentice on my laptop)
It looks like the collision geo on the nails is not very good and causing issues, changing it to 'capsule' in the bullet data of the RBD packed object, and also upping the rotational stiffness on the solver, allows it to getting closer to what i think you want. Attached the tweaked file - I also used the sop RBD solver (unlocked it to be able to go in and change the RBD packed obj collision to 'capsule')

Just downgraded to an older Studio version of the Nvidia driver and seems to have fixed things.
Appologies no doubt this has been mentioned somewhere before

Hello - I'm having some issues with getting vellum to do anything on a newly refomatted PC
I keep getting a crash following this error:
The PC is running win10 - Nvidea 2060Super and tried latest Studio and Game drivers.
Am running 19.5.403
Any thoughts?

oh brilliant! - i'm not near a copy of Houdini for a few days now but will deffo be giving this a try! Thank you so much for responding.
I know static noise is not always desirable, and my example was very extreem, but for indie users with limited processing power, i've found it to be such a useful option in Octane, but really want to make the gradual switch to Karma/Solaris.

This is what i mean - quick test sample from Octane, one with static noise enabled.
You can see the noise is just as bad, but far less distracting. Really no idea if this can be done in Karma, but it would be a really nice.

Hello - is there an option to have static noise like they have in Octane? This noramally means being able to get away with more noise in a render because it's not dancing about during an animation so much less noticable.
Or is the only option to properly sample renders to eliminate noise? And of course use noise reduction algos?
Thanks

Konstantin - Awsome as always (BTW love your Youtube stuff!)
So re the vex i think its used to group the points whoes i@ptrow are only divisible by 4 exactly, ie no remainder (using modulas == 0)and also have a i@ptcol equal to 2. So selecting the centre of the what will be the circle group. It's a very cleaver way to do it with the group promote - very nice!

@Aizatulin - Nice thankyou i think that will do the job nicley
@toonfish - Looks like the left one on your screenshot is the 'proper' way to do this. How did you acheive that?
Thanks both for your time! modelling really is not my strong point.

Hello -
What's the best way to do an extrusion with holes in Houdini?
I want to create a disk with lots of smaller holes, is there a way to set this up as an extrusion, or would I be better booleaning them out?
