Large render

[Peter Milner]

Here is virtually the same scene rendered at two different sizes.

The first is to go in a brochure (5080 x 1878 pixels) and the second is to go on the side of a large lorry (10808 x 5404 pixels).

As you can see, the large rendering is virtually black and even if I increase the brightness to maximum in the nXt image editor, it makes very little difference.

This machine has 8GB of RAM-- it's possible the thrashing is too much for it.  OTOH there may be a problem with the file.  Let me take one more look in a day or two-- see exactly where I'm stalled out-- and see if it's worth resending.

[Peter Milner]

That's the problem then. You're running out of RAM as opening the file takes up 10Gb.

[Roy Hirshkowitz]

Perhaps-- although I'm not sure exceeding the memory space by a few gigs should increase the load time from seconds to days-- something else may be up.

[Peter Milner]

The open file uses up 10Gb of RAM all the time it is open, not just at the start. So, if you haven't got 10Gb to spare, then you can't open it.

[Roy Hirshkowitz]

Nope-- Windows is a virtual memory system.  If enough RAM isn't present the system will use available disk space (swapfile).  It's just slower.

Any update on this one?

I need to get these renderings done very soon as the trucks are in and can't go out on the road until they've had their graphics applied.

[Roy Hirshkowitz]

Not really-- this issue may be open for a while.  I don't have an easy way to debug this right now.  Your current best bet would be to render as high a resolution as you can and upsample in photoshop.

[Peter Milner]

I've got a smaller file which exhibits the same problem.

I'll send it over via Wetransfer.

[Roy Hirshkowitz]

Thanks-- I'll take a look this morning.

[Roy Hirshkowitz]

Found and fixed (I think).  Render plus should be able to get a build out ASAP.  It will be 349.

There are still a few pixels messed up in the smaller of the two files-- don't know why but it's an unrelated problem and should be easy to clean up in PShop.  Haven't attempted to load the large one here-- but you should once you have the update (and let me know).

[Peter Milner]

That's great news.

The link to the download page seems to be broken at the moment.

I'll let you know, as soon as I get hold of the latest build, if it works with the big file.

[Roy Hirshkowitz]

Something's up with the Renderplus servers.  They'll announce the build when it's ready.
