Hi,
I was wondering. Does anybody know what the maximum bit resolution outputs are of the Blender render engines (internal, Yafray, …)? Thanks in advance!

It depends on available system memory (RAM), the complexity of your scene, how much memory is getting used due to image textures, and which OS you are using. Windoze has a higher memory allocation than Macs do but the “Save Buffers” option works on Macs and doesn’t on windoze (it’s a tile based disk caching process on the Output tab). Linux doesn’t seem to have these retarded little problems. You can also use the reallybigrender.py script for infinitely sized renders if you have the patience to stitch the images back together. It’s really cool and easy to use.
As far as I know, each color channel has 32-bit resolution. So does alpha and z. Of coure, if you want to save these, use OpenEXR file format, or tiff.
Hi RamboBaby, Myn.pheos,
The 32bit per channel is exactly what I’m looking for 
Thanks a lot for the info!
