I played with an old scene I never finished and I had the idea to try some renderings with the 3 main external renderers used today with Blender, I mean Yafaray 0.1.0, Indigo 1.1.13 and Luxrender weekly CVS Build from 13/10 (I also could have used Blender internal and why not Vray as an exporter is available to have a complete comparison, maybe later on).
So I rendered the same scene with each of them and ok, nothing special here but I’m curious to see who will guess which image goes with which renderer. So if you’d like to try just answer like for instance Indigo,Yafaray, Luxrender.
Rendering time varies from 4 hours for Yafaray, 3h30 hours for Indigo and 8 hours for Luxrender in a 1200x1200 resolution.
Edit : Here is the answer
Image 1 : Luxrender
Image 2 : Yafaray
Image 3 : Indigo
Some more information :
I didn’t spent to much time on the shaders, so the result may indeed be much more realistic. The purpose here was to get 3 results based on the same scene. Although, shaders should be tweaked according to each renderer. Another important information, the Indigo and Luxrender rendering were postprocessed (with neatimage) to remove the remaining noise, the Yafaray result did not required any noise removal, so at equal rendering time the Yafaray result would be better than Indigo and Luxrender one.
Some tecnical information :
Yafaray : Pathtracing, 48 path samples, AA=2, 5, 36
Luxrender : Metro + Pathtracing
Indigo : Metro + Bidir (mainly because it crashes without bidir !!?)
Lighting : Sunlight for each render engine
DOF : Standard with each renderer, not always the best solution, that’s why I usualy add it in postprocessing.
