[Bf-cycles] max render size?

[Jordan Miller]

naw, the rendered area is the proper size, I just get all black pixels
outside there. if I go down to 30000x2000 pixels it works fine and all
pixels render.

I want to render 60000x4000. how can I find out blender's hard limit
in image pixel dimensions?

yes this is for some wall art for an installation so I need a lot of
pixels, people will be up close to it. will be printing a large poster
at 300 dpi. right now I could only print the image at 150 dpi since I
am limited to 30000 pixels and I want it to be around 15' across.

so 60000 would let me print at 300 dpi no prob. if blender can output
a file that large (which it is) I just don't understand why all the
pixels wouldn't be rendered.
