What is the Max distance you can have objects and not get a visual glitch in 3D window?

[Miner]

I found that if I place an object (or anything) too far from my "work area" I see glitches in the rendering in the 3D window.  I'm trying to put a simple object about 90,000 feet from my building.  This object represents a mountain peak important that is important to the design for views.  When the object is visible the model near the camera disappears as I explore.  It's as if I'm standing in a bubble with a 20'30' radius and nothing within the bubble shows up.  

Has anyone else experienced this?  Has anyone found a fix?  All I figured out is that if I move the farthest object no further than 5,000ft away I get the "bubble" cutaway.

Thanks for your help!

Hi, 

I don’t know the exact value when the clipping starts to happen, but I also assume it is not the best idea to model far background as it would be in real life.

archviz modeling can sometimes rely on trickery and illusions to give a sense of depth and surroundings.

Why not place it closer and scale it down?

Or replace it entirely with a picture of it (using a picture object) and orient it such that it has a good angle for the camera.

And so on..

hope this helps.

@Miner there are a variety of distance things that can cause glitches... not necessarily two objects' distance from each other, but the project itself far from the origin.  Trying to model a distant mountain peak has worked for me in many cases...where I brought in Google Earth terrain (when that used to be easy) for both site work and showing views from the project.

You might want to look at the old 'cyclorama' technique that rendering and GDL master Dwight Atkinson (and David-Nicholson Cole) describes in this 20+ year old post as you can make a panoramic photo to apply to the cylinder and the rendered views from interior windows will be much more realistic than a model.  The steps will obviously be different with today's rendering engines/etc, but you'll get the idea.  You may need to illuminate the cyclorama (or make it glow) in order for the views towards it to look th way you want.  And, obviously, this technique of faking a distant view only works with a big enough cylinder (but not too big to glitch) and perspective/camera views:

@CosminF , thank you for your response.  You have good suggestions however in my situation I need to have the mountain in its exact location, scale, etc.  I am showing view corridors and how existing objects obstruct the view.  I can't achieve that with a static background or by scaling the object down.  

Much appreciated advice though!

I'll look into this.  Thanks!

Under 3D styles there is a view radius that may be causing you issues.

That didn't seem to make a difference for me.  Also, it wouldn't let me change the distance to greater than 328'-1 1/64".
