Obviously this topic is only going to be of limited interest so I’ve made a new post to keep it all together in one place.

Why Octane?

My choice.  I looked at a lot of renders.  And my eye was always drawn to Octane.  Something about the quality of the light - hard to put my finger on exactly.  The only other consideration was this - is there any chance that my carefully crafted Bryce scenes could be converted to Octane for final rendering?

So I got myself a GPU from Nvidia (well strictly speaking I got the graphics card from a vendor at Amazon) and the Octane demo from here http://render.otoy.com/ and had a go.  I’ve very much of the opinion that you learn things from your mistakes, success doesn’t really teach us very much, so I’m just going get on with it and you can draw your own conclusions.

Here to start with is the image from the Bryce scene I’m going to attempt to convert.

Oh David you traitor!How could you consider rendering in anything other than our beloved Bryce!...?  grin  wink

Seriously though, it looks like a nice piece of software. Do post some images if you work it all out.

Yes I thought I might get a bit of stick for perusing this project.  Here’s the complete series. And some renders to look at.

The second and last ones seem best to me, though the difference is quite small. Perhaps the sun is too white in the third one for being so near the horizon. The first one misses that shine-through illusion, the sun seems less bright.

Thanks for the feedback Horo.  Tired now, missed out on almost everything to get this done before I’ve got to tie my computer up with a monster render.  (Edit: After the first pass the prediction is 43 days - eeep!)

Sounds moderately long tongue laugh

The upper one is way better.

The upper one is Bryce.  Of course!  It may be weeks, months or years before I know enough about Octane to be able to push it as hard.  This challenge is about porting the scenes over.  And bit by bit learning some more about how Octane works.

Still rendering -  A power cut would be really unfortunate…

I see. So the lower one is Octane and the material on the rock is different. The shader in Octane is really very different from Bryce (more like the new one in Studio) and - considering this - you came up with an awesome result.

Octanes bump mapping falls a long way short of Bryce’s but Octane has normal mapping so… that might be better.  However, due to not being able to output the bump information from Bryce as 16 bit heightmaps the normal maps don’t look very promising so far that I’ve been able to convert.  I need to do some tests on getting colour from bump - in case those can be converted into normal maps…

Mostly I just want to get as much out of Bryce as possible, so far, primitives yes - but probably not metaspheres or trees.  Lattices and terrains.  yes.  I’m pondering how to create some volumetric effects in Octane… there’s lots of interesting puzzles to solve and it is also forcing me into unfamiliar parts of Bryce - like the export options for example.

Still rendering…

Bricks taken from Bryce scene http://www.daz3d.com/bryce-pro-advanced-lighting via DS.
Horo’s HDRI exported from IBL as a spherical map.
Wings 3D used to combine the allocated materials from the DS export.
Carpet texture from Genetica.
Normal maps for carpet generated with Crazy Bump.
Rendered in Octane in 35 minutes using the Pathtracing kernel.
16 bit png output, filtered for noise and converted to jpg using PSP8.

That looks very natural. Perhaps - just perhaps - there is a tad too much red on the white Legos. It could be a photograph.

The Lego bricks look great, very real.
I’m not convinced by where they rest against the carpet though. Maybe it’s just me but I’d like to see more shadow on the carpet.

Thank you for the feedback gentlemen.  OK, here’s another for you to cast your eyes over.  The bricks had about 40% of an SSS shader in.  In this one, I’ve pushed the effect over to 95% to try and give them a more gel like quality.  The same Bryce file was used as a source for the content of this image.

Certainly an improvement in where the objects interact with the carpet.
Love how the materials have turned out and the semi transparent effect.

It does look very real… All it needs now is a “choking hazard” warning sticker. grin
