Grainy animations

#3

well i always use user defined and automatic

but its like if i use crisp then the textures seem bad

how did Vue get the qualities they did with their demo reels?

#4

How are your quality boost setting in the atmosphere editor? Sky, fog and haze tab - before you ask. It should be up to 4, to get less grain in spectral atmospheres (with god rays especially).

#5

Well, im using GI.

#6

That has nothing to do with the quality slider.

#7

But i’ve heard that if the lighting is set to GI, setting the quality boost can increase rendering time exponentially. Right now its -1.5

I am having a similar issue.
Everything animation Ive rendered so far is giving me some nasty noise or grain of some kind.
I am not rendering a sky atm though, just a flat terrian with trees off in the background. I render through 3d max 9 and backburner. Ive boosted the settings in vue and in max and have seen only a reduction of grain, but no elimation of it. My render times are going up like crazy with every setting increase, and I dont want to be looking at a 1h per frame redertime.
The main thing that has given me the best resuls so far has been to set my antialias settings in max to 4/16/mitchell in mental ray, but like I said, it still has a visible grain.

Can someone shead some more light on this please?

I render my animations as single jpeg frames and compile them with Adobe Flash then convert them to QT with After Effects. When I first started rendering animations I got crappy results. Here is one of the first tests:

Since I have been rendering jpeg frames my animations have been looking a bit clearer:

Im rendering .png image sequences.
I dont believe the issue im experiencing is due to compression of the file format.
My office is blocking youtube.com though, so I am currently unable to see your examples…
Im doing more testing and hope to have a solution soon…

You need more AA to get rid of noise/flickering. AS for the atmo, as Wabe said, +4 is minimum with godrays. GI for animations? Hmmm long render times, even at -1.5, a low setting that may also add grain. Try GA, at -1.

You should also try soft AA strategy instead of automatic, it can help a lot, and use some distance blurring to get rid of noise/flickering of distant objects (in the advanced animation window)
Bump adds grain too, and render time. Use it cautiously.

So far these settings have produced the best result for me…

rendered at maximum texture Quality threshold from vue and with 16/64/mitchel in max.
The texture filtering was set at 20%
Anti-aliasing strategy was soft.
Subtrays per pixel = 16/64
textels per ray = 16/64

still working on this, im not satisfied yet…

#13

Frostics, are you sure Texture AA are necessary? They sometimes produce strange artifacts…

#14

Unfortunatelly, I’ve tried several methods and still cant get rid of the noise completely, as far as animation goes, movement of plants means noise! too bad

#15

No, you’re wrong, stalkeron. Did you try what’s been written in thids thread?

#16

I get the feeling that all those Antialiasing-Settings in Vue do not affect the rendering when you render with max and mental. I can do some settings where rendering out of vue looks ok, but rendering with these settings out of vue does absolutely nothing.

#17

Well, I don’t know it’s done in Max, but in C4D, you have the option to match Vue’s and Cinema’s AA settings, and I don’t use it, because teh Vue element are not properly AA’d, instead I use Vue’s own AA setting, and Cinema’s AA settings. Of course this means you need to know how Vue AA works, but it looks a lot better this way.

to bruno021: i’ve read everything on this thread and on many others. I’ve tried those settings and others, on animation I just can’t afford to use quality threshold around 80-90 and AA settings of 10-30… just to get rid of MOST of the noise… I mean, I need to use settings that are sometimes even higher than the ULTRA preset to get some noise out when having a camera flythrough… yes, you can add some distance blur and motion blur but still it’s verry annoying to the eye…

#19

Hmmm, in max it seems like you do not have a setting for matching the aa settings.

Is it in your Options-Dialog of the plugin aswell?

Here is a screenshot of our options, for those who are interested:

By checking “automatic” vue should try to match the mental ray settings.

Hi Zendik,

do you have an uncompressed version of your fly through - i am curious how long each frame took to render and if at all you got any flickering?

#22

Hi Solomon!
Sorry it has taken so long to respond, I have been away…
I rendered single frames to jpeg at 420X236 resolution using Chipp Walters Modeling render settings. Each frame took about 4 minutes to render. My machine is an Intel Pentium D at 2.80 GHz 1GB with a Nvidia 7800GS video card…
