Maxwell Render | Official public forum

Dear all
I am now using Maxwell for 10 months and love the program.
I will be happy to know if I am using it well and to learn from you how to improve .
I am in the interior field an exhibition design and using Formz.
I owned 1 license and 1 node

for example I attached here model I did this week:
• modeled in Formz
• resolution - 1300x921 px
• SL-16
• Time -600 Min (just to reach the SL)
• It takes 1H15m to render the model
Is it make sense? is it normal for that kind of model?
Please advise .


My machine:
main computer
Windows Vista Business 64-Bit SP2
Intel Core i7 CPU 920 @ 2.67GHz
12.0 GB RAM
NVIDIA Quadro FX 1800

one more computer
Windows Vista Business 64-bit SP2
Intel Core2 Quad CPU Q6600 @ 2.40GHz
8.0 GB RAM
NVIDIA GeForce 8600 GT


what I am doing (please advise is it recommend ) is using the other computer as node .

My main issue/problem ...
the final result has a lot of grains
I cannot afford to reach 1750X1240px (A4 150 dpi) the program show that in 20SL it will takes 8h to render +1 node
in the past it was easy to reach 2923x2067px when it was render in Formz .


Thanks to all helpers !!

Hello,

A few tips to improve your render time:

1. Use a nice HDRI for your environment lighting.
2. Make sure you don't have glass lenses modeled on your recessed lights with emitter plane behind the lens. If you do, delete the lens or make the lens be the emitter.
3. For your white objects in the scene have a material that:
Does NOT use a Reflectance 0 greater than 230
Does not use an additive layer for reflections (use normal blending)

Other notes:
I'd make that TV image an HDR emitter.
You should make your curved geometry have a higher polygon count.

That's all I can think of for now. Good luck!

Also if you are using Multi-Light, make sure you group the emitters as much as possible -- each emitter (or group of emitters) will take up extra render time in Multi-light... so you want as few as possible.

Also watch out for your Angle of View -- right now you are getting some unnatural perspective distortion... you want to try for a 46 degree (diagonal) angle of view whenever possible, which is considered "normal" (meaning similar to the perspective we naturally expect to see). You can find several Angle of View calculators online but I like this one:

hey bubaloo, I'm not trying to derail this thread at all, but does using IBL for the environment lighting always make renders clear up faster, no matter what you are rendering? I was just wondering about this question earlier tonight. Also, has anybody done visual tests of this in the forum? Say...render a gray model with emitter lighting vs ibl lighting...glass, doing the same, etc? If there has not been a thread about that, i'll def do the side by side testing and show the results!

I'm not sure about any forum tests, but in my experience IBL environments are faster to clear than emitters. So for global lighting, I definitely start with a good HDRI. Then add key emitters as necessary. It's just my workflow for most projects. I'd still love to see a side by side comparison if you want to do it.

Hi There,

My work flow is Form-Z and Maxwell Render as well. As Brian hinted on, I think is you material settings is what's causing the grain problem. A model like the one you have there should clear quickly with v2. Do as Brian suggests. He knows.
