Rendered Mode development

After some time without rendering anything in Rhino (maybe about 8 months?), I took a look at it again.
First of all, the Rendered mode looks so much better for me than what I was used to. I don’t know if it is because I was using V-Ray in the past and the materials were not previewing correctly (v-ray doesn’t care about some useful Rhino features, so that would be no surprise) or there was some development done?

Anyway, previewing scene in Rendered mode is much more eye-pleasing now, thank you for all the work!

To not make it all sweet, I need to mention about huge viewport performance drop if there is an Ambient Occlusion texture turned on in the material.

Are you talking about the Physically Based material in Rhino WIP?

Yes, this one.

Hi @Czaja,

Thanks for the report - we’re actually aware of this but we didn’t have a YouTrack item for it yet, so I created one:

I have an issue with selecting geometry in Rendered mode - there is a huge lag between click and selection.

Scene has around 400k polygons and uses 4k textures.

UI also acts very slow.

Hi @Czaja,

Can you give a link to the model so that we can take a look?


Can I send it somewhere? For some reason file is quite heavy. - 415 MB :grimacing: Also, it contains paid textures so I shouldn’t upload it publicly

You can use to upload confidential files and @DavidEranen will get an automatic notification when the upload has been completed. For completeness do add a copy of the link to this discussion in the comments section.
