Hi all! I made a quick scene to test the renderers i currently use, unfortunately i wasn’t able to reproduce the scene in maxwell so here there are only Cycles, Corona and Luxrender, If you want to do the same with other renderers i can give you the .blend file.
All the renderers stopped at the same render time.
Cycles:
Seeing the differences is really cool! I’d love to see the lighting setup. I can tell that the corona render’s global illumination was a little more powerful, seeing as the lines in between the plates disappeared.
The plates look like foam though in Corona!
The wood looks better in Cycles.
I’d say if I had to work with it, to clean up the plates in P.S. and use the Cycles!!
Hi Thanzex, I would like t have the .blend and try it with Octane Render.
Cheers, mib
What was the render time ? Share the blend file and I will try with Yafaray.
Render time for each one was 1:30 minutes, if you have a less/more powerful machine than mine (signature) increase or decrease the render time obviously 
In the file there are already the materials for corona, luxrender and cycles obviously, where you can look at to recreate the materials in other renderers
