Many thanks... the defaut Yon on the Poser cameras is apparently 850 poser feet.

But everything I've read suggests that this can be increased readily enough and Seachnasaigh backs that up above.

Obviously I'm trying to increase the setting WAY beyond 850 poser feet though. I seem to have to go up to nearer 20 or 30 THOUSAND poser feet for the whole length of the model to appear in Preview. So I may be hitting some sort of invisible ceiling?

Not sure why I have to increase the Yon quite so much, because by my calculations my model length is only coming in at about 8000 poser feet long. A bit under that in fact.

Bagginsbill's environment sphere, which Ive also been looking at, is 750 poser feet... but he says on his site that this is just to avoid users having to adjust the camera defaults.

I don't think I could use the environment sphere for the receding composition I have in mind... but I guess I may end up wanting a really big environment sphere for the background beyond the receding spaceship model! ;-)

I will maybe try increasing the Yon to just 8000, ignoring the fact that this still doesn't reveal the whole model in Preview, and then see how that renders...

Maybe I'm just hitting OpenGL limits / weirdness in Preview, but then max-ing out Firefly (at least on my system) by making the Yon as high as I am...

Usually though I find firefly just renders the inside of a blackhole for me, when it can't cope.

Anyone know any more about this? Any help greatly appreciated...

Thanks
