#7 AppCrash when exporting file to 4096px

[Anonymous]

After working on a skybox, i exported first to 2048px, no problem, Then tried to export to 4096 as well, and gave it a different
name, same export folder. It crashed pretty immediately.

Log excerpt:

This FBO thing is haunting me - NVIDIA GTS 250, 512MB, pretty new drivers.

I suspect this is a matter of memory on the graphics card. I'll try to add some functionality that can at least tell you if your graphics card will not have enough memory to do the export.

Got a similar issue when running in SLI mode with 2 NVIDIA 8800s. Crashes on export for 2k and 4k export. When SLI mode is disabled 2k and 4k export works fine.
