Render Region

[ok, I no speak english]
How render a complex scene, 5000x3500, in blender?
My computer crash (window): only if render a region, blender not crash.
So I request and obtain this script:
(Script -> Render -> Render region)
(thanks krypt!)
“This script will divide your rendering into smaller blocks, and render each block.
You can choose any number of subdivisions…etc”
Good script!

thanks for the link, there are a couple of other good scripts there also.
the render layer script looks very good, quite useful for compositing.
setting up for greenscreen/chroma key via render layers is one use i can think of.
