Scene bounding box is too large... - ERROR

Hi,

I’ve got this error messages on a couple of renders. What’s happening, how can I solve this issue?

Scene bounding box is too large, some shading artifacts may occur.
Scene bounding box is (minX minY minZ maxX maxY maxZ): -2.02073e+22 -416758 -2.02073e+22 129938 2.02073e+22 18761.9

Seems that your scene scale is too large, try and reduce it to see if the error goes away.

My scene is in the correct scale. It’s is a very large scene but I can’t scale it down. Right now it’s scaled according to real world measurements.

how big? pics, file?

The problem is weird because I have managed to render other camera’s from the same file but I’m having a problem with a few of them.

If I lower the resolution then it renders any camera… The resolution I have problems with is this one: 3840 x 2160

With this resolution I have no problems: 1280 x 720

The scene has approximately 600 x 350 meters and the file size is 464 MB

Have a read of this to see if any applies to you.

I changed the system units to meters and that seems to have helped… I had them in centimeters.

They are here: Edit>Preferences>Units>Unit Display: Meters

Until now I’m not getting the error… Seems that was the fix.

Glad to hear! :smiley:

The problem appears again if I have something selected in the viewport…

I’m rendering using the takes system…

The Render Selected option is disabled…

I guess I’ll just have to make sure I don’t leave anything selected before I hit render.

It actually doesn’t matter… the error persists.

Don’t know what the problem is. I guess it’s a bug.

What version are you using? Also, are you able to share the scene?

Corona 1.7 hot Fix 2. For the moment I can’t share the scene.

then delete everything that you cannot share and if this problem still persists, you can upload it.

This must be a bug, because the minX and maxX are something like 200000000000000000000 meters, which is getting close to the scales of diameters of galaxies… A scene would be great indeed. Or maybe find out what is causing the bounding box to become so large by repeatedly deleting more and more objects from the scene.

Do you have any Railclone in the scene? I had something similar recently. i.e. same corona error message and the viewports were behaving crazy as if an object was miles away from the origin. Worked out it was a simple railclone object causing it (when turned off the problem disappeared) . I couldn’t fix it so just deleted and rebuilt the railclone and that fixed it.

Edit - Ha! forget that, was scrolling through unread posts and didn’t realise this was a C4D post, so cant be railclone for you.

Yep, I don’t have any railclone as it’s C4D… I’m also using a Mac…

But it seems the problem only occurs in Macs because I have submitted the file for debugging but the Corona team doesn’t get the error I get…

2 Quadrillion KM, you certainly need double precision for that :wink:

We have a Mac in the office too, so we’ll try it out…

Great to hear that Cestmir! I hope you get the same error! hahaha I’m really desperate and don’t know how to fix the problem.
