CXR file format feature request

[Place]

Hi all,
I've got a problem: I have a lot of cxr files of (very) huge size - 5Gb for a 3k image, and 25Gb for a 5k image.
For what is my (little) knowledge, the cxr file format is the sum of all the elements of the lightmix (don't know if it stores all the other render elements too);
as i think the huge size reason is that each of these elements is stored as an exr image (I'm I wrong?),

So  this is my request for cxr format: something like a checkbox that can permit to choose a "small size CXR" with te beauty element
stored as an exr and all the other elements as compressed files (jpg, png...).

Is this something completly crazy or has sense for you?

Thank you,
Man

Well, the main aim of CXR is to use LightMix, Denoising etc. in post, in the CIE. So, the images have to be 32 bit HDR, which is why each layer is an "exr" too. Also, there are a lot of other layers stored so that Corona can work its magic in the CIE (rename the CXR to EXR and open it in Photoshop to see). With those being the purpose of the CXR, I don't think there's a way to avoid it being a large file.

Ok, thank you TomG.
