The second test of the interior in Indigo for Cinema 4D

N.G. · Post by **N.G.** » Mon Dec 24, 2012 8:01 pm

The second and more serious test render. Accumulated a lot of questions.
Rendering time (still is) 15 hours.
Questions are organized, and I will write later.

-through portals can not see anything (the sky) - how to solve?
-clipping plane visible from the other camera - how to solve?
-how to simplify the chandelier? (long believed) (disabled glass with a thickness for the rendering)
-how to simplify the lights in the ceiling? (light passes through the glass with a thickness)
-had more questions, but I forgot

You won't be able to see anything behind an exit portal. That's the nature of the beast. If you want to see the outside you'll have to postpro it in. I think you can do a "Foreground Alpha" ( in "render modes" in indigo interface) render to use as a mask.

On small objects where reflective and refractive effects of glass are not visible such as glass in front of small light sources or even windows, remove the glass to speed up the render process.

If you need to keep the glass in place and it is flat glass, then use Glass Acceleration.

Where are the light sources in that awesome chandelier ?
Perhaps post a wireframe. It looks like its made from glass cylinders. Use at least Birirectional Pathtracing. You may get quicker clearing of noise when using Bidir MLT.

Last, but not least. Beautiful renders and study of lighting!
That repetitive " noise" with the " indigo" label is really distracting

Renders like these deserve better.

-exit portal (seems to be understood)
-I immediately turned on the Glass Acceleration

-light located at the ends of the tube ... it is dissipated through the crystals ... I used Bidir+MLT
-I yet using the trial version :Р

I was afraid you'd say that

So in essence you have approximately 40 glass cylinders ( I admit being too lazy to actually count) on each side of this lighting setup with one light source on the end of the cylinder shining into the cylinder. That is a very complex lighting situation to evaluate for any render engine. Bidir MLT is exactly right to render this, based on my own experiments with complex luminaries.
Looking at this setup 15 hours does not seem so bad. If you do decide to get a full license and do this kind of stuff I'd recommend to get one or two additional computers as render nodes. No expensive graphics cards needed as Bidir MLT is not GPU supported. Two node licenses are included in a full Indigo license so there are no additional software costs involved.

Would you have a reference/ web site to this chandelier ?

Anyway, just in case no one has said it, welcome to the forum and have a Merry Christmas!

I figured out how to simplify. check it out. the result will show.

The lighting set-up in your renders is beautiful. Very warm and inviting.
I still really would like some link to that initial feather looking chandelier

There is an old German saying "Gut Ding will Weile haben", meaning "all good things to those who can wait". Well...more or less

23 hours, depending on the computer hardware you use of course, sounds long. However, again you have created a complex lighting setup, with lots of specular materials. If you are considering getting a license keep in mind what I said earlier in respect to the two node licenses that are included in a full Indigo license. For scenes like this Indigo pretty much scales linearly. Buying a second identical computer will cut render time approximately in half.

Looks great!

Thanks for posting the link to these lights.
If you really modeled these with the crystals inside I can imagine that you had to wait for an eternity for the render to clear up!

chandelier modeled exactly as in reality

I've been waiting a very long time ...)

it was necessary to include the aberration for the final rendering

Done. Have to wait for an update Indigo on Cinema4D.
