Hello,
I am new to SketchUp & Vray, and I am trying to create a 360 panoramic render to view on the google cardboard. So far I have gotten this far ( See image above).
I can’t seem to fix whatever is causing those white rings to render along the floor. The floor and the carpet are two different materials, with different attributes. It also appears when rendered in the normal perspective so I don’t think this is caused by the camera type.
Does anyone have any ideas on what is causing this?
Any help is greatly appreciated, thanks!
If you look on the floor plane, there is a weird… white speckle pattern being rendered uniformly across it’s surface. It seems to be rendering in more of a ‘waves’ or ‘rings’. I am wondering what is causing this to happen, as it seems to be radiating from the camera point.
Any ideas?
There are at least three of these lines in the render. It reminds me of a ripple expanding from where ever the camera is when I render. In the viewport, it looks normal.
that is strange. i first suspected some lights showing wrong, but i am out of ideas.
perhaps try doing clay render (override materials) and see if it is emissive or reflective material giving you that problem?
then remove some lights?
sorry, i dont have definite answer, but this is how i would approach problems like this.
I don’t quite understand it all, through a long process, the simple solution of raising the model fixed it.
Bonus, if you want to see how this is supposed to be viewed:
Save the image to your phone, download the app VR Viewer (For iPhone) or VR 360 Photosphere (For Android) If you have the google cardboard, you can view it through them. You can view it without Google Cardboard if you have an iPhone.
Nice work there! As a bonus, I’d suggest turning on Ambient Occlusion to give your scene a bit more photo-realism. Also, don’t use Spot lights that much. Personally I try to avoid them if possible as they don’t produce the necessary quality.
If you need to light your interior environment try using rectangular, omni or sphere lights + emissive materials. Spot lights give extremely sharp shadows, that’s why you see that wave-like pattern, because you have them hanging from the ceiling in a row.
Regarding those pesky white spots, they come from the artificial lights, mainly those Spots lights (if I’m not wrong). Under the Color Mapping tab in V-Ray settings, put a checkmark beside “Clamp output” and “Sub-pixel mapping”. That should get rid of them.
Very nice point @VahePaulman
I agree with you on that.
@betty, There are some websites that you can upload and share the link with. And they can be viewed with any browser. A bit easier to show to your clients as you don’t really have to tell them to get an app.
One is Theta360, a brand for 360 degree camera, but their “viewer” app works fine for these 360 degree renders on multiple platforms. (no need to have their product to use it)
*I used your image, let me know if you don’t want your image up there. Will be removed.
Another alternative is:
*I don’t prefer this one because the navigation isn’t as smooth
If you are on iOS devices I have had good result with “LookSee” as it it simple, but works (it works with Google Cardboard as well)
I have tried at least 20 viewing apps out there. This is what I have found. Let me know if you know others that work better

Thanks for the tip; I will definitely try this. I still don’t have much experience working with V-Ray or Sketch, so this is very helpful. Once I have a good render, I will post to show! @VahePaulman
I went through a process of of elimination, and part of it was deleting all of the spot lights in the scene, which made no difference to the output of those white spots. (Image of pesky white spots in earlier posts.) Also, wherever I rendered from, the white spots radiated away from, regardless of where the lights in the scene were. Apparently, V-Ray creates a “ground plane” when rendering. The floor and the plane were in the same spot and conflicting when rendered. The white spots radiating from the camera’s position was a result of their battle to be seen. Hence, lifting the entire model a foot or so off of the floor solved that particular issue.

I am always on the search for host sites and apps to view these renders on! Information on or about them is hard to come by. You’re right, theta is easier to navigate then the second link. But viewing it from my desktop, theta looks warped.
I will look into LookSee for iOS. I don’t use iOS, but the Principals of the firm, who are the people who show our clients these renders via the Cardboard, do. But it would also be nice to send them their buildings via a link for them to view on their desktop.
If you do find better apps, please send me a message and let me know! I’ll keep you in the loop as well.
