Indigo Renderer Forum

Heres another scene I've done, Notice the noise on the back wall and in other areas. I don't know if it needs more render time of if there I something I can do to fix it in SU. I had the scene render over night for 10+ hourse on 5 computers 3 dual core 2 quad cores. So I can't imagine that would be the problem. Feedback is much appreciated.

I don't think you're doing anything wrong. It just needs to bake for longer. Note that 1676 × 1114 is pretty large for Indigo, so one would expect your render to take a while.

Nice scene, by the way.

If light is coming from outside the room, use Exit portals!
You maybe have to show us your scene light setup :/

Also prevent full RGB 255 white, use a max of 80% (RGB 204) for faster noise clearing...

btw: nice szene, but the roll of paper needs some more polys dude
(also a top texture is done fast if you put such thing on a scanner!)

wow if after running on 5 computers for 10 hrs you still have this much noise there is definitely something going on. id follow ZomB's suggestions as well as giving some space to the fridge, adding a backsplash to the counter, and thickening it as well, and it looks like you also need some kind of wall-to-floor treatment such as a baseboard, hardware on the uppers, and i think i'd lower the exponent on the grout of the counter tile. cant wait to see your progress, go sketchy!!

That far back wall looks like it's not getting any direct light at all, and indirect via a specular bounce somewhere...

It does get direct light, as you can see a sharp shadow on the fridge. Also the window is reflected in the microwave. It seems to have shutters, which probably let the light bounce a lot around before reaching the actual scene seen by the camera.

And since we are after windows, make sure not to use real glass for them, or by definition the light entering the room will be indirect (caustics). As suggested exit portals would be the thing to add (and no medium in window's glass if any).

The kitchen is only a small part of the entire model. The model had been made up from 3D Laser Scan Data using a Scanner that collects billions of points per second. It was then registered then modeled. I do have other light sources in the house so that could be whats causing the problem? I'm not keen on what exit portals do.... I heard they increase render time for scenes that have interior lighting or something like that. I'm eager to learn and would love to here more from you guys. I can show you a screen capture of the living room facing the kitchen to give you a better idea of what other light is hitting the scene. I would normally render in a shell reducing my light sources but like I said its an entire house built from scan data.

I'm using sketchup black backround btw.

Could you elaborate more on this? What do I need to do step by step to fix this? Where would I want to place the exit portal?

He's only saying that if you want to use sunlight to light the scene.

What is your lighting set up now? Seems odd to me that you have that much noise using all those computers and rendering that long.

Is there anything else in your model than this scene?

doh, just read your post above.

I think that sounds like your problem, Indigo-if I'm correct- will render the whole thing, not just what you are seeing.

I know it renders everything but shouldn't turning off layers fix it?

Maybe if I Copy paste everything in to a shell and try rendering?

Anyway, I think the bump-wood is too high. This, in addition to not give realism, increases the time rendering.
