Stripes in Rhino rendered view

Rhino
1

Hello,

I’m currently using Rhino 8, and when I switch the display mode to “Rendered,” some strange stripes appear all over the model. Has anyone else experienced a similar issue?

Please run SystemInfo in the command line of Rhino and copy-past its output here.
BTW, could you please share this 3dm file? Thank you.

You probably will want to move your geometry closer to world origin.

@jesterking you are right; my geometry is located far from the origin. However, I moved the geometry closer to 0,0,0, and it hasn’t changed a thing.. Units are set to milimeters, and my goal was to model a complex of few buildings in the area (picture below) , that’s why this one is so far away. I know that modeling far from the origin can cause some issues, but how to approach modeling in such case? Should I switch to centimeters or meters?

Check out Objects Too Far From the World Origin [McNeel Wiki]

Regarding model unit: ask yourself what the required accuracy is? When doing buildings, do you really need sub-millimeter accuracy? If you model in meters with 0.001 accuracy you still get to the millimiter…

@jesterKing thank you for this article.

Regarding model units: I could certainly use meters with 0.001 accuracy, but I chose millimeters because I model a lot of small details. Using millimeters is easier and faster for me - for instance, typing ‘5 units’ instead of ‘0.005 units.’

However, thank you for this comment. I will check which approach suits me better: modeling in meters for the global model, or modeling in millimeters in a copy model and then importing the scaled model into the master model (in meters).

Just like I mentioned in previous comment, I moved the gometry closer to 0,0,0 and it hasn’t changed a thing. However, when I copied geometry do another empty model, the problem is gone :slight_smile: Thank you @jesterking.

Hi Aleksander -

Yes, it’s far, but not that far from the origin. That should just work.
When I open your model, it looks like this:

Hi Wim,

So I wonder why this problem problem occurs to me :face_with_raised_eyebrow:

Hi @Aleksander_Bachrouch
Just guessing here, but it could have something to do with the size of the shadow map. When displaying both really large and really small objects at the same time, the size of the shadow map will adjust to encompass all visible geometry - not just visible on screen, but all geometry visible in the scene; so even “off camera” geometry. If you’ve got “large scale” geometry showing at the same time, the quality and detail of the shadows on smaller objects will deteriorate accordingly, which might explain why the object shows just fine on @wim’s system.
HTH, Jakob

Hi again @Aleksander_Bachrouch
Just actually downloaded the file and found the culprit - your camera is set to a lens length of 68376.364mm, which is… insane. Set it it something more realistic… 20mm, 50mm, 200mm, hell, even 1000mm. The view starts cracking up around 1700mm on my system, but YMMV.

Wow :hushed_face:. I really don’t know how it happened. Thank you for noticing that. I’m not at the computer right know, so I’ll check this out later!

Jakob @Normand, I checked out and you were right. That was the lens legth, that caused my problem with rendering! Thank you once again :partying_face:.
