This project is due like yesterday.....

The first pic is how it should look. Rendered to screen at 1600x300.

The second was rendered to disk at 3200x300.

Now there's this dark dirt/grain all over everything. And now it's there no matter how I render it.

Global ambience was on in both pics but the grain is there even in standard lighting now. Nothing else is changed. But something did for sure.  Does anyone know what's going on?  Or how to fix it?

If it's been discussed before, sorry.

Thanks,

Oh and this is Vue 7.4. But it's the same in 8.

Did you try increasing the quailty of the atmosphere?
Are these standard render settings or custom.

Is it something to do with post render options? 

Additionally are you sure its the same picture you are rendering? It may seem like a silly question but in your first image, there are extra trees just above the chair and the chair and box are scaled differently. Additionally the left of the two trees is different from the first picture.

Be sure to uncheck "autoexposure" in the post render options, and have the atmosphere quality set at 1 or higher.

Lars "bigbraader"

Also, see if you're having "Volumetric sunlight" checked - if so, try using "No shadow on clouds" instead (in the atmosphere/sky settings).

Forgive me for interfering, but should you not increase the height to 600 when you increase the width? I would render it at 3200 x 600 and decrease the size in an image editing software.

Shari.....it was 600 for height. My typo in the first post.....

Some clarity.......What's boggling me here is the change between the two renders when nothing in the settings was changed by me. And only minutes apart. Render setting was 'Final'

Jonj....yes, same scene. I did take out two trees between renders, but other than that, same scene.

Jonj and Lars....I will double check my settings.  I didn't think about the post processing....maybe something changed by itself the way that screen will come back even after clicking 'don't show this screen again'.

It's happened with a couple of other scenes as well where my first render was fine, but a second render immediately following was covered with dirt and grain....

Thanks for your replies folks....gives me something to go on besides sanity doubting lol.....

M

Maybe you need to refresh the indirect lighting in the render options? It could be affecting the render.

Jon

Thanks friends! Problem solved.

I rushed home for lunch to check things out and everything was snuff except that the global quality setting in the fog and haze room had been knocked down to -7 of all things. i never suspected.....either there's a ghost in my machine or I'm completely senile with multiple personality disorder or...just plain daft lol....

At any rate, I know what to keep my eye on now and we're back in happy render land.  Thanks again for the replies......they always help!!!

Have a good one!

Glad you sorted this out. Oh and I really doubt there is ghost in your machine...-)

No ghost? Then that means....I'm a gibbering idiot!!  lol....Oh well...there are far worse fates!

As we know Mark - what an old support engineer said to ME once - 95% of the problems sit in front of the monitor. Keep that in mind! Good that it is solved - nice scene btw!

heeh usually it's something simple and obvious...if you knew where ot look for it! ;)
glad you got it fixed bud :)

Finished and delivered to happy customers......this is for a long wall in a rehab room of a prosthetics company. That's why the slight focal length distortion.

If anyone ever wants to turn their Vue images into murals, keep in mind sign companies that do billboards. They can blow up an image and adhere it to a wall for far less than some other professional options.

You know, I've been having this same kind of problem as of late. Vue will just randomly reset ceartain atmosphere settings, often after I import a large model into the scene. Hmmm.

It certainly can happen.  I once had Windows spontaneously rename it's .ini file with $%^* and completely disable my machine. Though the Microsoft techs were quite boggled they did confirm that spontaneous events like that can happen. There can be 'ghosts' in the machine.
In this case I could have sworn I didn't touch a thing but it being me sitting here in front of the monitor, as the fellas state above, I'm the most likely answer.   But I certainly am keeping a sharper bead on my settings now to see if it happens again.

I remember reading that as the complexity of computers has increased, at the far edges of things, randomness and errors come in, so that if two identical machines were both asked to find the value of Pi, they may end up showing different answers...
Twilight Zone music plays :p

on blowing up images, did you manage ot snag Genuine Fractals when it was on sale? :)

No I didn't....I use Fred Miranda's Stair Interpolation plugin for Photoshop and a tool called Kneson Imagener.  Seems to work ok.

Monsoon
ah, okydoky bud:)

alas I found Genuine Feactals won't work with CS4, grr, and now I re-installed Windows (to v7)
i don't have CS2 installed anymore and don't fancy reinstalling it, sigh (bougt CS4 extended upgrade)
