HI!!!
(i’m trying to replicate the tutorial on the left… but the ground plane doesn’t reflects the car in my Rhino rendered mode)… but it reflects the environment… … Is this the expected behaviour of materials applied to ground plane in Rhino8? (it actually works on Raytraced mode… but not on render mode)
reflections dont show in rendered mode, as you can see the tutorial also uses raytraced, what does reflect in rendered is just some standard light i believe
hi!.. thank you for cheching out… but the screenshot of the tutorial uses rendered mode… Kind of the “sale point” is that rendered mode in Rhino 6 is very good on itself… and the presenter kept showing how good visuals can be achieved “instantly” in render mode… So I was wondering if that was removed in RHino 8… or if that is too a bug
you can switch the realtime display engine to cycles if you want to stay in rendered mode, that will only add raytraced rendering either at least for some parts if i am not fully off, so i am afraid in rendered mode there are no reflection without that so far.
actually scrolling through the video it does appear like it has reflection in rendered mode. @nathanletwory do you know anything about that? i also had the feeling that worked at some point i am a bit confused.
No, I’m Raytraced / Rhino Render, not Rendered mode. Rendered mode is the domain of @jeff and @DavidEranen
Groundplane reflections only work in Rendered mode if:

Thank you, Jeff.
I wasn’t aware of that. I applied a custom material to the ground floor in my latest render, following your example. However, it would be great if the ground floor could support other materials as well. Could this feature be added to the “wish list”? It would help achieve more consistency in the scene’s behavior across both raytraced and rendered views.
Said that. I want to ask you if could you please share the scene (or the scne settings) of your render… It looks amazing and mine I feel is not looking great yet.
It looks like you just need to have better lighting setup, and maybe a better environment image. The number of lights, the type of lights, and the surrounding environment can all make a huge difference in the results… and maybe even a little color 
The example I used is just Jorgen’s (@Holo) “Mini Cooper” model from his benchmark script (Holomark)… I just turned the groundplane on and added a reflective material to it.
Here’s the file…

And this is the environment texture it uses…

should i complain or is somebody going to tell me that all that will be good soon 
why is that so? because of metal?
Yes. The functionality was never added/included during the rewrite. And “popular demand” is usually what drives features…Since we’re on SR17, and this is the first time it’s ever been mentioned (afaik), I’d say it’s not a very “popular” feature…but I could be wrong.
I believe I added this in V5, and to this day, I haven’t seen or heard many users talk/complain about it, and now that Rayraced mode is a thing, reflection trickery in the display seems to be a thing of the past…again, I could be wrong.

Thank you very much for the resources… as you mentioned… a huge improvement with the light setup. I was playing too with the mini model… and when I switched to raytraced I realized all were custom materials and rendered very bad, and setting that to PBR was not “one click process”… Could that be a request too? (better translation of custom materials to PBR?
Another thing here is that I realized that the ground plane is not placed in the same position in raytraced and in rendered… (screenshots attached)…
And one last quesiton, is about the behavior of “bump” in PBR materials. Tires are completely flat in my PBR version and I dont understand how or where to control that… (I’m attaching the model back here)

that explains why i had the feeling it was there before. i skipped v6 and with v7 i did not realise and soon v8 was launched. well i dont need that so urgently, not sure what it really is useful fоr, a quick preview without having to render? or even a serious analytical tool of some sort? knowing that some differences between mac and win are accumulating again i am just a little worried and a little jealous, very little in this instance admittedly.
Tools > Options > Advanced. Search for BumpStrengthFactor and BumpDistance. Increase, toggle away from Raytraced and back after changing these. For this model distance of 100 and strength of 10 work quite well.
Using normal maps for this in PBR will work better though, at least in Raytraced / Rhino Render.
thank you Nathan… do those values refer to something… like units (nonetheless in this example it is evident that the bump never gets to 100 mm)? I know this is getting out of topic of the ground plane but… which values could really provide an extreme bump… or what should I tweak? Thank you
I think there is still a lot of use cases for rendered mode, not at all a thing from the past. Both Cycles and rendered mode are amazing. but I think they should behave as close as possible to be user friendly…
On the other hand I can Immagine rendered mode can be handy for animations (some exploded part animated diagrams,. etc)… Also it can validate the “opinion” of friendliness of Rhino for new users starting in 3D modeling… (like students with not so powerful computers).
Finally. about animations…is there any solution inside rhino? (other than recording screen while navigating snapshots?)
There are simple flythrough and path-based animation tools built into Rhino… You can find them using the Animation toolbar or by using the appropriate commands… Just start typing “Animation” in the command line, and you’ll see all of the commands available.

Okok… thank you for the tip of the Animation toolbar. Do you know if the snapshots animation can be saved too into frames? (or that only works with a screen recorder?)
