hi.....

i am working out on maxwell from day1.....until now i haven't succeeded in getting rid of noise in maxwell images.......i have played with all the settings like f-stop, shutter speed, and film ISO.....i have also added lights and proper light intensity to them..... please go through the attached images and let me know about the render and light settings..........where am i going wrong.......

thanks in advance and cheers

You're not going to get a clean image from a closed interior in 15 minutes with maxwell. Make yourself a sandwich, put on a good movie and sit back for about 40 hours.

There are many things you can do to reduce the noise in your renderings, however Maxwell is quite possibly the slowest render engine on the planet and you should be prepared for very long render times especially when dealing with interiors. I use 10 dual core machines rendering in cooperative mode to render out all of my Maxwell scenes, at a resolution of 3000x2550 I can get an interior scene to an SL of 16-17 in about 15 hours. This is the equivalent of rendering on a single dual core machine for 300 hours.


-Make your emitting surfaces as lowpoly as possible.
-don't enclose your emitters in a dielectric object if possible
-Make sure the emitter isn't intersecting other geometry
-don't use pure white (255, 255, 255) in your scenes try something like (233,233,233) because the pure color will increase the amount of noise .
-use AGS glass where ever possible
-unless you need them turn off caustics
-don't use sunlight and physical sky, a HDRI or skydome with a sunlight emitter will produce much less noise.
-hidden emitters can reduce noise

i am sure you can get a good looking exterior image in 20 - 30 mins... an interior hmmm ....how long till your patience runs out?

hi maxer.....

wt does this sentence mean?????

"hidden emitters can reduce noise"......

and also please tell me smething about the scene scale......does it realy effect the lighting output in the image??????? my scene is in feets and inches.....i have put .254 value....is this value correct?????

cheers

Maxer

Hidden emitters are just that emitters that are hidden but still cast light, basically they are invisible to the camera.

Scene scale should be set to 1 always.

Maxer, I thought .254 was correct for feet/inches. Isn't Maxwell set to calculate based upon the metric system?

I've been told this for the FormZ plugin, maybe others are different?

nivvu

Even i too was been said before that .254 scene scale is must for feet and inches scene...........and u r saying tht it should always remain in 1......so which one is correct..???? if i render that interior scene with .254 its rendering totally dark......and if i render with 1 then its cmg out well.......

now watz this..??? how to decide on scene scale for a particular type of max scene....

please advise..
nivas

Maxer

Before version 1 came out you had to adjust your scene scale but not any longer.
