More details?

I am successfully building against FreeImage 3.15.3 on Windows. You may need to use QT 4.8.x due to different versions of libPNG being included in newer FreeImage and older QT.

Sorry about that, it's a bug in Mantis (our bug tracker). Hopefully I've fixed it now.
May contain traces of nuts.

Bug in the bug tracker... Hmm, smells like a recursion to me. :)

A spectral one will be much better still.

CUDA? In Lux? No, thanks.

Is there any particular reason that CUDA isn't being used? Is it based solely on a dislike for nVidia, or is it that OpenCL is just superior?

CUDA is a closed standard. Using a closed standard in an open source project doesn't make very much sense.

Plus I think most (all ?) LuxRender developers have AMD GPUs (bought with their own money, it isn't like we are sponsored); using CUDA would be hard :lol:

I'd say that if CUDA supports AMD or INTEL GPUs we might reconsider if it happens to be superior to OpenCL, but neither seem to be the case.

Hi,

Please note that there was a nasty bug in early builds preventing reading from standard input (used for example by the Reality plugin for material preview).
The builds have all been updated with a fix, so please redownload if you need that feature. Sorry for the inconvenience.

NOTE: The max. depth of eye and light paths in hybrid BiDir has a HUGE impact on the amount of memory used. I think the Blender exporter uses a default values of 48 and 48; it is deadly for hybrid BiDir. If you change the values in something a bit more reasonable like 16 and 16, you can cut the amount of memory used by 4-5 times;
