EXR half precision not applied to extra passes?

Hi,
I'm rendering extra passes along with the beauty in a non-multi layer exr format but with the EXR half precision on to save disk space. The Main pass seems like a normal file size for 1080 rez but passes like Post are nearly 5-6 times larger yet not much different in terms of pixel data. Is it possible that the half precision toggle isn't being applied to all passes?

Thanks
Yaniv

I am checking the Octane API, and it seems that the EXR half-precision feature is only available for the multi layer EXR files.

Hi again :)
I am getting very big files with half precision exr even for the main beauty pass, not just extra passes. Could you also confirm this please?

Octane Plugin/Standalone 3 alpha 6

Thank you

Yes, the half precision is only available for the multi-layered EXR files. The .exr files not included in a multi-layered file don't support this feature, even the beauty pass.

You could test a multi-layered EXR file only with the beauty pass in half and full precision, to see if the file size is the same.

I see. Is that a standalone limitation? Why would it be limited to multilayer only?
Having to transfer renders to clients or compers over a slow upload connection (not to mention disk space) forces me to have to manually resave all passes as 16 bit exr.
Any chance this can be added to include all exr passes?

Thanks

Currently this is an Octane API limitation. Only the function to save the multi-layered EXR files has this parameter.
