New progressive rendering

[Javadevil]

Hi,

Just been testing progressive rendering in 3dsmax 2011 and finding it really quite useful.
I could render a lot of high res stills using this method.
One thing that would make it even more useful would be a resume button.

For instance you select your sample settings, set off your render it finishes and you realise it needs more time.
Being able to up the sample settings and hit resume would be awesome.
Just like unbiased rendering has a resume feature.
If Mental Ray could save out some mental ray image format that keeps the sample info you could even load up the image at a later date to resume rendering.

cheers

how did you get progressive rendering to work in 3dsmax?

is the "progressive rendering" in max 2011 interactive like the script in maya?

+1 for this!
i don't know if it's technically doable, but it would be pretty helpful

HI,

As I understand it, Progressive rendering does not take advantage of distributed rendering, only computes the main color channel, and your scene basically needs to fit in memory. I'm putting together an article on it. I see it as a nice way to get a preview of a scene but might not be useful or better than mr for big images.

Hi Jen,
I did some tests on distribute/satelite rendering and your right it doesn't work with Progressive AA.
But maybe one day it will :)
Matts tests on scenes with lots of glossies and DOF is where progressive AA really shines.
I still don't see it as a faster way to get feedback as a lower AA setting renders quicker for me.
Maybe when 3dsmax can use the subsampling it will be.

cheers

I guess Progressive rendering is not interactive in max. :confused:

I found 2 Scripts in maxscript.chm in 3ds max 2011, for IP Rendering and Progressing rendering, it look short than found in Ctrlghost. maybe someone test it.

Yea, those scripts work great. The settings are not persistent and saved with the scene, so you are better off with ctrl.ghost if you want the settings to be there when you open the scene again, or want to network render.

Progressive rendering doesn't give you the ability to interactively 'scrub' an area of the image to force refinement in that area. mr just does what it does.

I have got both the max script, and ctrl.ghost set up. I cant figure out how to use the progressive rendering mode once it is active. Can someone give a more detailed example of how to turn it on, and then what to do next?

How do you actualy view the render window once progressive rendering is active? what are the steps to do this?
