OctaneRender 2020.2 for Houdini Beta build 2020.2.0.2 RC7

[juanjgon]

Love the SOP level geo!

For some reason I can't get the copy's colors to show up. If I remember correctly, I used to be able to do it with an instance osl or the rgb4k_map in the tex folder by putting into albedo...not working anymore for me. Any help? Thanks.

Here it seems to work fine. Have you enabled the attributes options in the copy sop?

Thanks,

Thanks for your work.

Hi Juanjo,
this release is crashing Houdini as soon as I hit either IPR or Render.

This can be a problem related to the OCIO configuration that we are investigating. I'll send you a pm with more information.

Thanks,

Hey,

sorry for the noob question - could you explain what SOP level packaged geo is and how it works?

Thanks so much!
Best,
Gregor

This feature makes possible the automatic instancing of the packed geo instances that you can create for example with the copy sop.

Check the attached scene for example. With this option disabled, all the objects are expanded to full geometry, but with the packed geo option enabled, each object is rendered as an Octane instance, saving memory and scene extraction time.

Hope it helps,
-Juanjo

Hi!

How is this auto-instancing supposed to work? I can't get it to set up properly.

On the left is the instance variable approach, and on the right the copy stamp with packed geo approach.

[juanjgon]

Do you have the option to pack geometry enabled in the copy sop? If you share the scene I could take a look at it here.

Thanks,
-Juanjo

Yes, and it's enabled both in copy to points and copy stamp nodes.

I can't attach the exact file I'm working on but I have attached one with pig test geo that has the same issue.

Thx!

[juanjgon]

Hmm, but your OBJ node didn't have the option to instance the packed geo, probably because it comes from an older plugin version. Once added and enabled, everything works as expected.

Yes, that solved it! Perfect.

Thanks!

Hello,

I noticed this version introduced a bug when using the "forced phantom" option in the Octane ROP for rendering an animation. Only the first frame is rendered correctly. You can check in the attached file that the sphere becomes visible again from frame 2. Simply render it to disk.
It used to work fine though.

Thanks for the hard work !!

Will this build work with the stable release just posted?

And did they fix the vertex color attribute bug I reported earlier?
