Rhino 8 Feature: Rhino Render Updated

Rhino Renderer Updated

Rhino WIP now has an updated version of the Rhino Renderer (CyclesX).

The most recent WIP releases of Rhino on Windows and Mac have an updated rendering core based on Cycles 3.5.0.

The key difference between Rhino Render V7 and the version in Rhino WIP is speed. The core renderer has undergone a significant update, and show ships with GPU accelerated rendering cores for AMD cards (HIP) and Metal on the Mac.

What this means is that on Windows you should see speed improvements of about 2x…while on Mac, we are expecting 10x the speed at a minimum.

Please feel free to test your models on Rhino 7 and Rhino 8 on both platforms and post the results here - including render times. For like-for-like comparisons, it’s typically easier to use the “Render” command rather than Raytraced viewport mode - but both are accelerated in the same way.

Have fun! Happy rendering on Rhino WIP.

does that also mean that i can take advantage of all gpu cores from an m1 ultra and maybe even use cpu additionally?

Personally, I am waiting for dispersion and caustic for jewellery stones. ! is there any hope of it appearing in Rhino 8 ?

Probably for Rhino 9


Yes to all cores for an Ultra. No for CPU combined.

It’s good that the renderer R8 is fast, but there’s no point if the renderer can’t make it look good. :sweat_smile:


Thanks @Andy,
Any chance for a Test Scene. [something that is packed with all the settings/textures/lights… so it is same on any machine.]

I would get Holomark from @Holo . It comes with the car model that you could try.

It looks like it’s Windows only

At least the version on food4rhino

The .rhi is just a renamed .zip file. Download it and look inside for the files.

I did have to update the old-style materials though to look good. After a couple of minutes fiddling with materials and geometry I came up with

(devoting more time to the materials and other render settings probably will yield better results)

(Updated the file and render after a bit more tinkering).


Thank you Nathan, this is great !

What would you recommend as a reasonable “production” quality and size to test the render?

  • I have not done any proper rendering n Rhino in the past [it was too slow. Plus I had a very old computer] So I was using Keyshot and Blender [both on a rendering beginner level]

thanks a lot

I would have used a floating viewport with set size, but Rhino on Mac doesn’t know how to do floating viewports unfortunately.

Instead, maximize the HM2_1 viewport and try to get it to say size 2400x1500. Then switch to Raytraced and see what time you get.

When everybody renders with that size in the viewport we get the best indication of performance across different hardware.

1m13s @ 2400x1500 on M1 with 8 GPU cores.

I see.

Man, that was hard to control on the Mac. This floating viewport possibility is not on the menu either.

Anyway, here one with floating viewport saved

[it says viewport size 1470 x 1600 on the updated render test file]

What settings would you suggest to test a production quality in the Rhino-Render?
here’s what I get for Raytraced with this new MBP:


On my computer the latest WIP opens with this message:
Screenshot 2023-07-10 120958

after any changes to the environment, the raytraced display mode is total black.

That plug-in is not longer supported in Rhino 8. There will have to be a new one built for it

  • Andy

So the black raytraced display mode is not connected to this?

I think it’s unlikely…but possible I guess. Only way to find out is to remove the plug-in - which I think you can do from the Package Manager.

After some tests I think I can narrow down the problem to the following: as long as I take a new file and don’t set any new environment, the raytraced displkay mode seem to work as expected.
If I change the environment, it goes completely black (only showing the viewport for a brief moment when for example rotating the view. As soon as raytracing begins, the viewport turns black.
