Friday fun

[rickeloy]

Had some spare time last friday and put together a small scene to test both V-Ray 3.0 and Corona.
The scene is no biggy, but I wanted to try a few things. For instance, I wanted to test the Material Converter with a couple donzen different materials. Found some discrepancies, some weirdness with anisotropy, but all fixable. The other thing I noticed was a small problem with the displacement: Corona seemed to simply ignore the mapping already applied to the object, which was kind of weird. On the bright side, I thought "what the heck" and replaced the displacement on the rug with real fur turned into geometry (21 million polys). Corona passed thru it like a breeze. So sweet!
Also did a few captures on different moments just to compare how noisy the pic is as time passes and found the scene to be completely noise-free after around 40 minutes (which is lightning fast compared to V-Ray, which took 2:30hrs to finish the same image).
Another thing: the same scene rendered MUCH slower when I had AO included as a render element. Anyone confirm that?

CANT SEE ANY VRAY COMPARISONS HERE???

Didn't post the V-Ray image, thought this was not the case since all you would see was a clean render and pretty much the same quality.

It would be very interesting to see the VRay image, if you still have it, even if the differences are minor!

Here's the V-Ray version...

This is sstupid, you compare 2 images with 2 diffrent camera settings, one has post and other does not.

You waste people time by this, also you materials look mostly straight "Converted"

[rickeloy]

Look, Tanakov, in case you did not read the first post I was not comparing both engines. I just wanted to see how the converter behaves in a somewhat complex scene (the original materials had some intrincated settings) and specially the displacement. Thought this was important to figure out for me since my workflow is 100% based on VRay and if I'm to consider making the jump to Corona I need to be sure everything works in case of need.
Never wanted to compare the two pics. If that was the case, I'd have posted both side by side (which I didn't, I just posted the VRay version because people asked me to). Not reading the original post and stoping by to criticize something that was already stated by the original poster is a waste of time and just plain stupid, imo.

I'd appreciate it if you could post possible problems (with descriptions and - if possible - stripped down maxfiles) in the converter thread :) I can only fix the issues that get reported ;)

welcome to my world ;)

I ended up fixing the few issues I found, so I don't have them anymore. But I'll keep it in mind next time and post these there. ;-)
