Hey guys,

What version of EXR does Clarisse render to?

I've noticed some features are missing like "autocrop" where the image size is reduced by using a bounding box. Maybe this came through with 2.0 and Clarisse is using 1.X?

Thanks,

Dan

Hi,

Clarisse is CY2018 compliant
https://www.vfxplatform.com/

So it's using open exr 2.2.x (not sure about the minor)

Bounding boxes (or "data windows") are a relatively old EXR feature, I am quite sure it existed before 2.0.

Not every application necessarily implements the whole feature set of the OpenEXR (or any other) library regardless of what version is used. A feature which exists since 2.0 from 2013 is the ability to write subimages instead of channels ("multipart exr") which gives you the ability to read these selectivly without the need to transfer the whole image. Unfortunately, few renderers actually use this feature so it always makes sense to set up a post render process (e.g. with OpenImageIO) to make huge renders digestible for composting.

It's 2.2.1 to be exact. ;)
