We're having a problem with producing large images for print using resolution multiplier (200%) and/or antialiasing set above medium. LW will chug along for 12 hours or so, a portion of the image will show up in the image viewer window but there's not a finished large image to be seen.

Is there another way to better maintain sharp super smooth object edges?

does the render window indicate that the frame is done? or is it(LW) just stopping?
are you F9 rendering or F10?
suspicion: you are rendering at a size larger than the image viewer is capable of displaying.
well it can display it...you just cant see it, think about it , lets say1280x1024 @200%2560x2048
is 35 inches at 72dpi....the window at1280x1024 is already near too big to display on a 21"
so you began to see where we are heading here.
have you used the save as feature from the image viewer window to save the file as a psd
and then open in photo shop? to see if it is actually complete?
the viewer save option is ok for comps but
on big stuff i generally do a save as rgbfile(render options)/f10 render, the image viewer is just slowing the render down anyway.
for smoother stuff ,,,MO'Polys(subdivide)...or if its a "nurb" set your render subdivision level higher in object propertys
hope this helps

Are u sure its the final render window you are looking at?
Maybe u are looking at the render in progress window?

Check with the render options

I'd consider buying another RAM card and bumping it up to 2gigs worth, especially if working in massively large resolutions is what you do.

Also, in the camera options panel, click on 'Segment Memory Limit' and allocate more RAM to it.

Thanks for the input. We have been using the render in progress viewer and have had no problems at lower resolution/antialiasing. However with the larger images, the window indicates the frame is finished, records the rendering time etc. but no finished rendering to view.

We will try the suggestions.

Thanks again.

not to over simplify,

to get a finished F9render to view from LW, you must set the render display(render options panel) to image viewer, (Unless you like trying to figure out what happening by looking at the render in progress window ).once LW finishes, the image viewer with your image, should pop up and give you the option to save from the file dropdown.
or.....set frame range to start and end on the frame your rendering
under render/ output files tab you can check save rgb and choose where you want to save, name etc. HIt F10...and use photoshp to view finish.
otherwise you get nuttin.
12hours?

Hi Cheryl-

I've had the same problems with larger images... I'd fall outta my chair after rendering for 10+ hours only to see that it completed - but no image. I 've done just what longchin suggested, use F10 for the bigger images... and turn off the "Show Rendering in Process" and the "Render Display". That'll do the trick.

Just to add another "quirk" of using F9 for large renders...

I also create work for print and therefore hi-res images. Sometimes hitting F9 will complete the render but display a black screen in the image viewer (well a portion of it anyway). Saving the file works fine as it displays in PS.

On a side note I recently needed to render an image for a high resolution poster print which maxed Lightwave out at 16000x16000 - any chance of LW upping that figure in v8?

Jeff,
take a look at this,http://www.lizardtech.com/solutions/photo/
go to genuine fractals print pro..... upsampling with ZERO image degredation.
this is the best thing since canned beer=)and has saved me literally thousands of hours,
of waiting for LW to finish big print rez stuff, not to mention saving my arse when the client shows up and "wants it bigger"? it is worth its "wait" in gold.

Thanks Tim - Looks like an interesting little nugget - shame it's not for 10.2 yet I'll have to check it out when they get round to releasing the update - thanks again!
