Objects far away are invisible
« on: June 23, 2008, 10:07:56 am »

In my space battle animation objects very far away are clipped off:  I have set Z_Far to 100,000 and more, yet large objects at beyond 12,000 meters are invisible.  Is there a limit on the distance that can be rendered?

Just ran another test:  they are not visible when rendering with OpenGL or Scanline, but they do render in ART.

Art ignores the Z near and far values. that's why you can still see them in ART.

if you changed the X_ far under the view tab, that won't make a difference in the renders.

in scene mode go Settings > Environment. at the bottom the the screen that pops up you will see a button that says "Advanced", click on it.

now you can set the Z_near and Z_far for rendering in Scanline and OpenGL.

Thanks.  I set the Z-Far in both the View settings and in the Environment tab.

I set the Z-Far in both the View settings and in the Environment tab but still no far objects render in scanline or OpenGl.  Is there any other setting I've missed?

possibly fog, if you're using that. or maybe a background image.

No fog, no background.

Does anyone have a fix for objects farther than 12,000 meters away bring invisible to the scanline and opengl renderer?

I have never tried to model something so big.  Could you have found the outer limits of the Anim8or universe, perhaps?!?  I would suggest scaling everything down a bit, as painful as that may be.

Leslie of terranim8or fame should know. He worked with stars etc so I'm sure he would have found the limits at one time.

Post a question on the org site in the terranim8or section perhaps?

Perhaps just scale down everything in your scene.  I don't see a need for the scene to be so huge...

Rescaling them is not an option.  I am previsualizing animation for a different program using the coordinates.

Does anyone know how to get far objects to render in OpenGL?

I'm sorry, I can't help with this.  It's possible you are striking a limit within Anim8or, or at least within the renderers.

i'd guess that if there is an absolute z-far limitation, then steve would know about it and would be able to tell us - unless it varies depending on the power of your hardware, though i'm not sure how that would affect it.

Could you have found the outer limits of the Anim8or universe, perhaps?!?

this thread reminds me of that moment in The Truman Show where he crashes his boat into the horizon...

I think there is a z-limits bug or two in Anim8or that could be causing this.  I'm looking into a fix.  You should be able to set these values.
