How to dump render layer into files ?

Hi,
I use blender+cycles to make interior CG.
I can’t find any method to dump render layer buffers (and reuse it a few days later).

  1. Does anyone know how to do it ?
  2. If blender didn’t implement this function, how to suggest developers to implement it ?

Thanks

Render to Multilayer format.

There are other options but using a multilayer openexr format is by far the easiest to set up and handle afterwards.

Great!! It works. Thank you very much ~~

I have find a good tutorial about how to use OpenExr Multilayer.


One problem is only “render animation” will dump files, “render image” won’t.
Hence I set the start and end frame to 0 in the timeline window and use “render animation” to replace “render image”.
