OTOY Forums

I'm testing the 1.20.1.17 version of the Octane for Rhino plugin.

I started with some small scenes of a few objects which worked ok. I'm now trying to render some objects from files i already have. Curved staircases, architectural interiors with lots of objects. Rhino and Octane seem to hang with these larger files and I need to use Task Manager to quit Rhino to make my computer responsive again.

Just wondering if people have been using the Octane Rhino plugin for large scenes? Is there a gallery of images from the Octane Rhino plugin?

Also, I'm wondering if my hanging issue is simply due to my graphics card (Quadro 4000)? If I add a better Cuda card would i be able to render larger scenes?

Thanks,
Andrew

Hi Andrew

With the current version, if you exceed the plugin polygon limits (I think it's 10 million polys), an exception is raised, but you can continue working OK (the next version allows you to set the max polys, and give a more elegant error).

If you exceed you graphics card memory, you should get a Cuda error (error 2 from memory), which the plugin will report. However a Quadro 4000 is pre GTX 500 series (I think!), so may be it is manifesting in a different condition, resulting in the lockup.

How much VRAM do you have? 2GB should get you around 15 million polygons (which is > the plugin max polys).

Would it be possible for you to send me a scene which locks up on your system? Then I could try on my system and give a better diagnosis.

Hello Paul,

I was facing a similar problem recently, is there also a limit on the polycount per object?
A few day ago I was trying octane on a complex train project, to optimize display performance I often join all meshes sharing the same material (in rhino this can totally boost the display speed).
I got this error and certain objects did not appear in the rendering after voxelation...

Is this per Object limit raised in the next Version?
It would also be nice to have a error message like "object xxx exceeds the maximum amount of possible polygons per object (1.000.000) - try to split object into several parts"

best regards Andreas

The limit can be user-set in the next version, and the error handling is much better. I think the current version is 10 million per Octane mesh (and if you set Live Geometry ON, those meshes will be treated as separate Octane meshes).
