Let’s see your best results you achieve with the rhino renderer.

Hi Paul, wouldn’t it be best to use the same challenge model?—-Mark
Nice Idea 
Changed the post 
Are there any rules? Can you move this? Assume no post?
This sounds fun, given I know hardly anything about the new Rhino Cycles, and little about the old one either.

Here a quicky:
Rendered on M2 Max with 64GB, 50 samples, denoise pass enabled after it was done, 4k. Time to render 14.37 seconds.
Why not adding the same point of view for everyone?
btw… I’ve got things to do tonight. Love it!
Point of view and “camera lens” is part of a render IMO so I beg to differ.
But seeing the same side of the knife is a good point so it is easier to compare.
I tilted the object a bit so that it made more sense in the environment.
But I do think that point of view and side should be open for change, pretty much everything except for the geometry of the object.
Say someone wants to put in a block of wood with a partial carving in, sure why not. Part of rendering also is the environment, where is the object. It all will create the ambience, mood and feeling the person is going for.
I wanted to have this small piece under the knife so that it felt more grounded. Other than that, just some basic lighting and texturing. In the end I’m not that good
Here’s a quicky. Cool knife!
Rhino 8
Edit: Some info:
Very NICE!!!
Are we sure is pure Rhino?
and is DOF allowed ? 
Why not, anything Rhino Render can do should be allowed.
For instance, if you know how to look on this forum you’ll find how you can do bokeh effects like this (yes it still works in Rhino 8)
Here’s my (Doffy) attempt.
Yes tooo much DOF.
This is
R8_Knife_Rhino_Render_Skysurfer.3dm (2.7 MB)
if you want to give it a try.
Dof is a viewport setting, it is activated in the original file.
Just don’t select anyting when perspective is active and look at the object properties page.
Problem with dof is that the focuspoint isn’t a point in space, it’s a distance from camera. So rendering with dof is like shooting photos in the '70’s with a manual lens
It’s too late and I forgot the viewport DOF.
This the image without it.
Thanks @Holo (I’m changing the original post.)
This is about as good as I can get. I’ve not used Rhino Cycles in anger yet ever, so I think it’s a shade overcooked. I spent ages battling geometry that kept getting randomly displaced due to Rhino PBR faults, having to reopen the document to rest this, fighting with why Viewport and Render are not the same result (until I restarted). Doh!
PBRs come from ambientCG, and the background is a Studio background from PolyHaven. The rest is whatever Rhino can make.
This was good fun learning though. All Rhino, with all effects applied in Rhino Cycles. Not sure which is the better outcome really. Thanks for the model, I wish we had such challenges more often (so then I can moan I don’t have time).
Forgot to add, this is Rhino V8 Cycles.
Absolutely stunning!
This is an awesome idea! Recently, I realized that if I do get into rendering it’s probably going to be via cycles for multiple reasons. I’m also learning more and more that focusing my attention towards just a few selected programs is quite advantageous. And I just don’t seem to jive well with the UI’s of the various renderers out there. It’s cool to see what can be done basically out-of-the-box. My renders always look terrible but I’m also overdue for a hardware upgrade (that will help make up some of the gap).
These renders are looking pretty amazing. Definitely looking forward to future mini-challenges.
Fantastic Images! You make me doubt using blender at all 
For now Blender beats Rhino in terms of material creation - our RhinoCycles doesn’t have all the shader nodes that Blender Cycles has, nor is there a way to create custom materials - I suppose maybe GhShaderNodes might work? I haven’t looked at that project in ages and I don’t know if it still works to be honest.
