Hi, Blender uses a regular C api for every module. You can browse the code for our exr reader here:
http://projects.blender.org/scm/viewvc.php/trunk/blender/source/blender/imbuf/intern/openexr/?root=bf-blender It has regular buffer reading support, multilayer, and tile based saving. It's all pretty straightforward to do with openexr. Most work would be proper integration I guess. I'm also very interested to make sure Gimp layers read/write would work nice for Blender as well :) We can discuss that outside of this list of course. -Ton- ------------------------------------------------------------------------ Ton Roosendaal Blender Foundation t...@blender.org www.blender.org Blender Institute Entrepotdok 57A 1018AD Amsterdam The Netherlands On 11 Apr, 2013, at 10:09, Felix Ulber wrote: > Hi there, > I also in the process of writing an OpenEXR loader for Gimp/GEGL.
