hmmm, where do i switch this? but iīm wondering why i didnīt have any problems rendering the other scenes iīve been working on in shaded mode....
Tools/Options/Global/real time drivers - switch/toggle to directx
BUT perhaps you don't have enough memory?
I also tried your chor - shaded - and had no problem with opengl (winxp pro).
I also tried FINAL, 1 pass, and 2 pass (no shadows) - no problem - except for first 2 frames when doing 1 pass (would get error message something like "Unhandeled exception in Hash/Mov" image io plugin - but could click ok and still would render. When I did FINAL 2 pass, I did NOT get the error message at all. (render looks quite nice - interesting lighting, setting)
I also notice that the chor is set to do IBL - but there isn't an image specified, with AI=50%, AO=100% -
perhaps try changing global ambiance type to color (white), and AO=0%? See if your system can handle it.
EDIT: And I also see that some light is doing volumetric -that might be causing problem but I could not find the volumetric light. Also Fog is set to ON (turn off?)
