I'm also going to buy a new graphic card specifically for Indigo.

So I have a question: is there any specific advantage in the CUDA implementation and optimization over OpenCL?

Basically, are high end AMD/ATI graphics cards a viable option, or do we need NVidia because of CUDA?
Thanks,

Short answer: because i'm an engineer, not an artist. :wink: Longer answer: my scene is simple, but it's procedurally generated and i need full control on the dimension and positions of my objects. While sort on topic: are there any plans to support CSG in future releases? CSG is great to generate p...

Haha, no there isn't any relevant exporter, I scripted the scene by hand in XML.

While on this topic: is there any specific advantage in using NVidia GPUs? Like Indigo for CUDA being more optimized than OpenCL? Otherwise I was thinking to get a good AMD card like a Radeon HD 7970, since several tests have shown them to be faster than NVidia's direct competitors, in OpenCL based ...

Yes, that was exactly the problem, thank you!

Hi, I've noticed that if i enable GPU rendering (OpenCL), emissive materials (which i use as light sources) are not rendered. They still light up the scene though, just the emissive objects themselves are invisible. If i use the same Path algorithm, but running on the CPU, then the scene is identica...
