It would be insanely helpful for those of us working with complex scenes for Podium to limit its render export to geometry that is visible (on visible layers, not hidden, etc). In very large scenes the export sometimes takes longer than the actual render.

Thanks,

It does actually, the number it writes stays the same, but there is an export time difference.

Do not forget to use Geometry catching!

Do you mean only render what's in your SketchUp viewport?  To me that seems difficult, if that's what you mean.  For example, how would light be calculated or shadows of objects that are not in the viewport.  I'm not saying this is a bad idea.  It's been debated a lot.  I just don't think there's a good solution.  We just need to figure out how to speed up the geometry processing, I think.

No, I understand that objects outside the viewport need to be included.

Thanks Nick. I see that the export time is slightly shorter despite the number remaining the same. However it seems not entirely proportional. A 38 second export from one scene on full got reduced to 20 seconds with one cube still turned on.

I do use geometry caching, although I find I almost always invalidate the cache between renders by tweaking a texture or something like that.

Ah well. Maybe it's a pipe-dream to do this kind of work on a Macbook Pro.

Dave, I noticed that exporting is 32 bit process and it uses only one core. The only possibility I see is if podium could load .skp file and render since there is no 64 bit SU yet.

As I understand it the exporting or the Processing Scene is done by a Ruby program and can only done this way and that is a 32 bit process and limited to one core.  As far as I know, there's nothing that can get around that.
