No idea what exactly "only renders with the values assigned" means. Renderers (at least current ones) indeed works with RGB colors with premultiplied alpha (and premultiplied is the term we stick here to). Render engine should be a black box for the pipeline actually, it could use any color space,

As a wise man said: go deeper! The actual issue is not about being unable to apply any sort of color transform when saving float buffer (which you shouldn't do btw in properly set pipeline). The root of the issue goes to the fact, that renderer always outputs stuff in rec709 space (or in your lang

Toby, I'm not quite sure to understand what you are asking. You would like the color transform "baked-in" EXR ? IMO, exr should always be linear, especially if you have to move it around other parts of a pipeline. The ability to baked transform into a LUT seems more reasonable no ? 2013/7/8 And

Sergey, It is crucial that the artist have the option to save EXRs with the color transform chain directed by the artist. Without this, it severely limits the ability to use EXR as a image interchange format between blender and other parts of the pipeline. Sincerely, Andrew On Mon, Jul 8, 2013

Nothing is broken here. All the float images are saving in scene linear space by intention. Adding a way to save in different color space is in TODO list. On Mon, Jul 8, 2013 at 7:38 AM, Troy Sobotka wrote: > Is there a reason that the color management transforms do not work on EXR > files save

Is there a reason that the color management transforms do not work on EXR files saves? Seems broken. With respect, TJS ___ Bf-committers mailing list Bf-committers@blender.org http://lists.blender.org/mailman/listinfo/bf-committers
