Indigo looks more like under water to me :)
To me too.

Based on my very limited experience, the commercial unbiased renderers have a bit of a long-term advantage when clearing more complex scenes with lots of objects at high resolution. To me, it seems Indigo does fine at the beginning then for some reason kinda stops clearing while the others carry on. Otherwise, Indigo wins for simpler scenes and smaller res as its images have a clarity and sharpness others can't match.

I think, that's 'cause Fry changes it's render algo, after every update.... while Indigo's stays steady at qrmc...

try a 100,0000 ray bounces or something :)

to me I find the Bump mapping in Indigo a bit odd....

here is another comparison - Camox's studio setup tweaked with another person's spheres :)


Fry rendered for 1hour, and Indigo 50mins. Allowed an extra 10 for Fry's use of Micro poly Displacement. Used Bidirectional MLT in Indigo, and it rendered pretty quickly with 100,000 ray bounces to boot :)

I have attached the original Fry render which is supposed to be at 6500 white balance, but it sure don't look it! :P
I had tweak it in Fry's tone mapper - removed 10 units of green and blue, and added 10 units of red, then added some slight contrast boost.

The caustics and reflections in Fry took forever to show in the main render, I could see them in the small preview image, but not in the main image until 30mins in. Indigo already had them within 3 mins and the caustic refractions as well!!
Don't think the caustic Refractions are ever gonna show in Fry.....

Used the Aluminum preset in Fry for the other spheres, and the Aluminum (al.nk) NK file in Indigo.
Bumpmap from the tile bump map image - which worked really well in Indigo. Just a slight -0.002 setting for the front sphere and a -0.02 setting for the rear sphere to emulate the Micro poly displacement of Fry. Used negative values as Cindigo's exported meshes are somehow reversed...
And bump map values were hand edited in, as there is a bug in Cindigo that won't register changes in bumpmap into the scene file.

I take back what I said about Indigo's bum map, it looks good! :P
Matches well with Fry, but the Fry's right sphere is actually larger from the micro poly displacement of 15cm.
MPD in Fry rocks! It's slow to warmup when previewing materials, but when actually rendering I didn't notice much if any warmup time increase and the render didn't seem much slower or more memory hungry!
Will Indigo get MPD as good as Fry's one day..? :wink:

You can see this dark edge on the Fry's spheres. I think it lacks energy compensation or something that Indigo has 8)

I also attached a 15min render of the Maxwell version just for a quick comparo. I'm not a fan of the washed out Maxwell look. What the hell is going on with the bumpmap on the right sphere....? And the white reflection overriding the bump map? :shock:
At least the reflections and caustics are there

cool test :D Indigo and Fry look pretty similar, besides the lack of caustics in Fry and the MPDsphere on the right :D - where the stone-plates should be higher, on the floor, you clearly can see the difference between bump and MPD...

I think, you should have used more polys for the spheres - they're quite edgy...

about the picture: It's not the 2nd I can't see, in your post, but
"Again, a pic, that I can't see - the second on this entire forum" ;) - and I don't have a tiny glance of an idea of why I can't see them... (as noone else ever seemed to have that bug :()

maybe right click on the missing image and show pic or something :)

I need to try more MPD in Fry!
It is probbaly the best MPD I have used in any renderer, quick and memory light!

Fry really needs NK support and a simple Phong model, and better refractions and glass...
and faster indoor rendering - ironic that it developed exit portals to speed up interiors, but is in itself much slower than Indigo who nabbed it's exit portals :P

oh and fix the tonemapping and white balance....

Looks like fry is missing some paths...
Note the lack of orange highlight in the sphere.

this is something Fry has that not too many other renderers, especially unbiased ones can match...MPD 8)

used a recent test scene which I have posted before

cylinder on the left is your basic texture + bump map

middle cylinder, I used the same texture and bump map, but also applied the bump map to the micro poly displacement channel. Tweaked the map with the very nice array of image modifier sliders in Fry - stuff like contrast, clamping off the upper and bottom ranges etc, and then displaced the cylinder by 10cm

right cylinder was displaced by 30cm with a modified checker pattern that's built into Fry - Fry has a row of procedural patterns you can tweak and use

All this slowed the render speeds by half, but there is a lot of displacement and it would be hard to model the kind of detail you get in the 2nd cylinder....looks just like real stone! Although some funny things are happening on the cylinder tops :)

image rendered for 1 hour, pretty much as it came out of Fry with the supersampling option on, but I also changed the colour balance like in the above image.

There appears to be some smoothing problem with the right cyclinder, but it had smoothing on originally being a curved object, but after displacement you get both curved and flat surfaces now.
The water detailing looks strange.....

very nice MPD!
Just got an idea :) - do you think, there's a difference between Bumpmapping in Indigo and Fry?
Dunno, what *could* be different, but the test wouldn't be too hard to do :)

Why there are no water caustics?

yeah bump mapping is a little different, I supposed I could do a test
Why do you ask?

suvakas - probbaly one hour is not enough for it to show, that's assuming if it will show though :D


here is a close up on the MPD detail

amazing details O.o - doesn't look like the same kind of stone, any more, though....
