Hi,
Firstly, thank you for your effort! Octane plugin for Houdini is getting better and better Nevertheless, I have some suggestions.
It would be great if we could select different bit depths for AOVs in single exr files. Currently we're wasting a lot of drive space for 32bit multiexr's when color data mostly can be 16bit. Drive space is cheap but if you want to send 4k 32bit renders via internet - it's a pain.
Second thing: there is some Camera Metadata in multi-exr files. It's simple and great solution! Could you add it to single exr files as well?
Best regards and have a nice day,
Wojciech Czub
