What color space/tranform is the HDR setting


Wondering what the hdr checkbox does in Embergen, it seems to crush the alpha a bit when rendering with exr.

What I have noticed when outputting exr, is that setting the background alpha to black is necessary as well as using the hdr checkbox. Without these two things the alpha will have unexpected results.

Anyways just wanted to know what the hdr toggle does. does it convert image to linear space?
and with it off is the image output srgb?

Thanks :slight_smile:
