Instancing and hair rendering within Solaris not working yet?

[miguel65WPA]

Hi,

I can't seem to be able to render any instances or hair within Houdini Solaris. Is this something that will be supported at some point soon?

Thanks!

Miguel

Hi Miguel,

we have a ticket for supporting curves in the render delegate : https://github.com/Autodesk/arnold-usd/issues/19 .

Instances of meshes and volumes should be working in Solaris. Could you please share an example scene?

Cheers,

Pal.

Hi @Pal Mezei

Thanks for your reply! Great to know there is a ticket. Any idea of when will you tackle it?

Find attached a simple scene with my instancing issue and a couple of images of what I get with Arnold and with a different renderer.

This is using HtoA 5.2.1 and Arnold 6.0.3.0

Are you using Linux? I just fixed a build issue that affected the instancer and other parts of the render delegate on Linux.

I switched the curves ticket to "In Progress" on GitHub. I'll keep you updated.

Hi Miguel,

I believe your instancing issue has been fixed with the latest HtoA / Arnold 6.0.3.1 release. The work on curve rendering is progressing, although quite slowly.

Attached a screenshot of the current version of the code, which is not yet merged into master.

Hi Pal,

I can confirm the instances are good now, thanks.

Cool! It's so nice to see the progress with curve support! Thanks so much for the update.

Hi Pal,

Do we have a timeline for curve support yet ? really looking forward to it

[pal.mezei]

Hi,

curve support was released with HtoA 5.4.0. There are a few limitations, but nothing major. Please let us know if you find any bugs!

I just checked the docs of htoa,it still says not support,maybe it's not update yet. and thanks Pal, I'll test the curve.
