The Cardboard Chair

A model i built in Moi3D yesterday, it's supposed to look like a cardboard chair which you can pick apart and carry with you and then reassemble again. It's perhaps not perfect but it been a looooong time since i used Maxwell (been waiting for plugins to get fixed).
The scene is setup in C4D and rendered at 1600x1200, it's still rendering until around midnight tonight when it'll be finished, i'll be updating this post with the finished render when it's done.
Maxwell Render 1.5 version (Rendertime: 9h 24min 39sec)
..and for those of you who like to compare stuff

here's the same rendering done with Fryrender beta 1.7 (Rendertime: 9h 24m 37s)

Max, your images suffer heavily about AA due to improper resizing.

Tom, they haven't been resized. This is the real resolution so i don't know where the AA issues comes from :/ ..it looks the same in the renderwindow.

Interesting. Then I would say it should be about UV mapping.

Yes, it's probably a combination of the mapping itself and the object which is boosting these jagged edges you see. There's that typical interference pattern due to the mapping consisting of rather thin lines and i guess it's not AA'ing the textures, just the mesh itself.
But anyways, personally i like the Maxwell version. It's warmer and better in my eyes, and it has more depth to it.

Nice- nice comparison as well.
That aliasing effect happens all the time in images I work on regardless of where they come from (renders, captures etc.). Tight regular patterns start to show that effect as they get smaller - it's hard to get around. You might find softening it up slightly in those areas helps, but not necessarily. I've never been clear on why sometimes it happens and sometimes not.

Very Happy
Good tip - thanks - but Max did not scale down his shot, and I have seen this issue in images at original size. It' sometimes seems that it is the size of the texture in the image, not the the size of the image that makes the difference.

oops, sorry. I probably read too quick

Brett: Thanks, and yes that pattern is the interferrance (probable typo)

which you get from tight patterns. It could be avoided by antialiasing the textures better, i'm not sure how this is handled by Maxwell so i'm guessing it could need a slight improvement when seeing this result. But the fact is you see the same problem in the other engines result, it also suffers from AA issues in just about the same places.
sms: Thanks for your tutorial

i'll keep that link for the future. But as Brett said they haven't been downsized, they're at their fullres. Btw, pretty good tutorial you made.

So - Maxwell is 3 times faster than FRY??
Why would anyone use Fry?

by Maximus3D
Not quite Kurt, in this particular test which is a 'exterior' type test with only 3 emitters, a bent floor plane for that typical studio look and a simple 1 layer lambertian material with 1 colortexture and 1 bumpmap it renders fast and at high quality (little to no noise) on both engines.
As you can see quality comes very close on both engines, not really that much of a visual difference here. However other types of tests will show other and bigger differences but that's not something i'm gonna get into. No need to fight anymore which engine is the best and which sucks, i came to the conclusion it's a waste of time to argue about that.

..they're both good!
Why other people use it i can only guess.. i let that be unsaid here. I work with both engines and both pleases/displeases me with their positive and negative stuff as i use the engine that fits best for whatever i'm gonna render.

oh and btw, the Maxwell rendering had only been running for 2 hours and 55 minutes when i posted it here. The Fryrender image had been rendered for 9,5 hours so there's a major difference there in the time they rendered.

i don“t think maxwell is faster than fry.
if you take a close look at the maxwell rendering, it is not finished yet, not as sharp as the fry one.
but this is a different discussion...

I updated the Maxwell image in my first post as it now been rendering for 7 hours 5 minutes.
