color stripes on the render image

Re: color stripes on the render image

You could share your Rhino file (without the model details), so that we could test it at other computers. If there is a bug, I would like to find it.

Thank you very much Micha! I have already sent file on the first page this thread...

and here is a scene: scene file

Re: color stripes on the render image

Hmm, I tested it and got a light banding only. But if I click with the RMB in the image and look at the pixel info, than the color jump at a band is only one greystep. So, if I can see one greystep, than for me it's a question of the monitor.

I'm not sure it's important against banding, but I would change the values:

* enable color correction for input
* never use a so low burn value
* 60 IM interpolation samples are a lot, I use 20..30 most
* LC sample size 0.02 is quite high, I use 0.01 .. 0.005 most
* LC "use for glossy rays" could be enabled

Re: color stripes on the render image

Thnx Micha for a tests and advice! I must try it..

And i has befor one question..

......Is able, then qualitty of a render influence harware ? I try a render on "home-PC" (before in work) and i think the result ist better like from work-PC....

It is possible..?

I think no. If the setup is the same, than both output images should be the same. If I would test it, than I would compare the output images at the same screen.

I was it tested, therefore i have this quaestion....I note, then i use like primari engine DMC, then the banding is out too....maybe is problem in irradiance map....://

Re: color stripes on the render image

Hmm, and there is no noise that hide the banding? Maybe one of the ASGvis moderators could test it.

Re: color stripes on the render image

I set high qualitty of a render to minimize a noise that not occured distortion....

One more thanks Micha for your time in this problem!

Re: color stripes on the render image

Here is next one image.....

This image show then the reflection is not affect a banding...:/

And unfortunately, HDR format (16 or 32 bit...) is not solution too (

Re: color stripes on the render image

I found one solution of this problem....When i use rectangural light and the choice "store with irradiance map" is off, then the stripes is out.....

But rectagural light make problems in interior - sometime nonsense bleaching in negative corners, like here: http://forum.asgvis.com/index.php?topic=7331.0
