CoronaPattern playground!

Not sure if it's bug, or limitation, but when the pattern is limited to certain material ID, it disables displacement for the rest of materials, that should not be affected by the pattern. Attaching example images - the only difference between them, is pattern modifier being on and off.

damn that's very smart use of pattern. would make nested scattering easier:   (tree+modifier)xScatter

[romullus]

Yeah exactly, if it would be possible to scatter hierarchies, then we could could detach the leaves, then group, or link them with the trunk and be done. I was very pleased to find that the pattern can be restricted to specific mat IDs, but this displacement limitation is kinda ruining everything.

This is currently expected.
Unfortunately, from a quick chat, it seems that fixing it would be very difficult. Let's hope it's one of those impossible things that our devs can do.

Not the issue related but maybe worth mentioning: a quick test showed that using Opacity on large number of faces is 2-2.5x faster than using Pattern.
With scatter this will of course get multiplied by some factor.

Thanks for the clarification. Now that i know that quick fix/improvement is unlikely, i can plan my assets accordingly.

I noticed that too, but opacity will never look as good as real geometry, when the object is very close to the camera. That's why we need LOD in the Chaos Scatter, we could have hero trees with displacement, the pattern and everything in immediate proximity to the camera, less detailed trees with opacity some distance away and then more heavily optimized meshes at the horizon.

Hi,
It would be nice to see an option smth. like CapHoles to prevent these holes.

Hi guys, will we see this issue fixed in corona 9 release?
Thanks

Sorry, but that would mean developing a feature in 5 days (counting the weekend), and we are already feature-frozen, so this is not possible for V9.

Forgot to say thanks for adding the real world scale option. That makes things so much easier. Such a great feature.

[vizset]

Just tested simple window with osl map.
Awesome feature! Thanks!

The thought went further
Let's try this with single collapsed train mesh (3 million polys) on 2 km height solid

upd. is it possible to resize youtube thumbnail to small?

Love Corona Pattern! Thanks Corona team!!

hi guys - im getting ridiculously long IR times with corona pattern - ive got a ryzen 3970x - not sure if im doing something wrong?

Hi,

Please send a video-recording of the issue, and provide as much detail as possible.
Attaching the scene where it happens can help as well.
For better tracking and resolution, I would suggest sending a ticket to us at: https://support.chaos.com/hc/en-us/requests/new, and attaching all relevant information and files.
Thanks.

Experienced the same situation.

Was trying to pattern some fibers object (created from splines) on a chair. IR was pretty much unusable.
