Okay... switching to software mode preview rather than OpenGL sorts out the weirdness that seemed to be related to the Hither setting... with greeble / nurnie details dissapearing etc.

So the Hither is fine left at the default setting. That's definitely just some OpenGL bugginess on my Mac.

Then, also if I scale the model down to 50% I manage to get the whole thing to render.

But I can't get the whole depth of the model to render scaled to 100%.

In attempting a 100% size render I'm positioning the camera at DollyZ = 10000 to get the whole model visible.

Hiding the ground plane and hiding the background plane from camera etc.

Using Poser 9's "Even 360" light setting, that has 3 infinite lights.

But, even setting the Yon up to the max amount of 860000, I still get clipping at the exact same point along the depth of the model... the exact same point as if I set the Yon at, say, 50000.

Same issue by the way if I leave the camera DollyZ at zero and z-position the model back by 10000.

Weird? I'd have expected, if it was a clipping plane issue, then varying the Yon would vary the point that the render of the model cuts off at?

Currently downloading that Enviro Kit mentioned, to see if playing with that maybe sheds any light on matters... will see how the size of that scaled up to 1000% compares to the scale of my model.

Anyone else come across this sort of issue trying to render very large scenes?
