Hi, we would like to render at very large resolution that exceeds our RAM.
When we use shift lens with offsets of +/- 100 % we can divide one rendering into nine (9) renderings.
If there was a way to increase the offset to values beyond 100 % like it is possible in LuxRender, we could divide the rendering into more than nine segments.
Is there a way to set the offset to values beyond 100 %, at least as a command line option?

not saying whether that should/shouldn't be an option, but you could do a series of region renders rather than using shift lens.

This might indeed be a solution as long as the size of the rendered region requires as much RAM as a regular rendering at the same size would.
That is, if rendering a region of e.g. a tenth of a 20.000 x 2.000 Pixel rendering (Origin X=0 End X=2000 Origin Y=0 End Y=2000) requires as much RAM as a 2.000 x 1.000 Pixel rendering.
This would solve our panorama task.

I can't say that it's exact. My guess is that it might be a bit more because it's rendering that portion of the scene plus a huge black area (whatever isn't in the region)...but how much RAM can it take to render out a huge black area?

Unfortunately it did not help: the amount of RAM needed for a small portion of a large rendering resembles a complete large rendering's need.

To the developers: Could you implement a shift lens offset beyond 100% (just as LuxRender)?

Couldn't you do this by first rendering the 9 segments, then moving the camera target and render the other segments? Would be a bit like taking a panoramic photo in real life.

Yes I could but I absolutely need a flat projection plane, and in case I changed the target the next 9 segments on each side would be projected on two horizontally turned planes.
Is there hope that this feature is already implemented but hidden or is there a physical simulation reason for not implementing this?
