That looks abit more like it. Tonight or this afternoon Ill render it again and see if chnging the IR settings helps. Otherwise I'll post all my settings.

Im using the latest Vray.
The last render I did had the RAM usage up at 3.24 gb, I was holding my breath waiting for it to crash but it didnt.

Cheers mate

You have mentioned "The latest Vray" as your VfSU version, can you be specific? There's been several times where people have thought to have the latest, while they actually did not. And I also don't know if that means the beta or not.

thomthom

Ah yea - the version number is now located under Preferences -> Extensions -> V-Ray for Sketchup

There is an memory leak in this version however. So as you render after render you might find that memory is not released. Version .83 should be released right about now - but I'm not sure if it fixes the memory leak. But it does fix an array of other problems.

Sorry Thom for being vague
The Vray version is 1.48.66

It dosnt say what version Vray is in the options anymore
So had to hunt for the installer.

Ive finished work and am about to test changing the IR settings.

You were total right about the IR settings

Im now rendering double the size of the last render at 4096x3072
and it is using a whole 1gb less memory.

I didnt realize that it would make that much difference.

Have you had any experience in printing large images. If you have, what
output size do you think I would need if I wanted to print to 1.2m x 2m?

Thanks again for your help Thom

It's sad but VRAYforSU is the oxymoron. Use original max version.

It really depends on from where it will be seen. Such large images usually are seen from further away so one usually doesn't need the same resolution as A3/A4.

1.2m = ~47.24"
2.0m = ~78,74"

Say you print this in 100dpi - slightly larger than screen resolution:
47.24 * 100 = 4724
78,74 * 100 = 7874

But that might be very high resolution is you are at a distance.

1.2m x 2.0m has an aspect ratio of ~1,667
4096 x 3072 has an aspect ratio of ~1,333 - so that means some cropping must be done unless you change that.
Also, 1.2m x 2.0m is portrait, and 4096 x 3072 is landscape - so I'm not sure what orientation you are going for. ?

I'll assume the output to be 2.0m x 1.2m - landscape.

So if we use the full length of your render and print that to 2.0m, the resulting DPI is:
4096 / 78.74 = ~52.02dpi

Getting a Max license - not a cheap solution...

And as for the semantics: can't say I see how one can define "V-Ray for Sketchup" as an oxymoron.

There are some good examples of oxymoron in english wiki that depict my statement qiute well: Serious Joke, Sweet sorrow, Happy depression...

"Metaphoric oxymoron" ?
