Seems like "Half precision" checkbox do nothing
I supposed that I get a 16float image but seems that I get 32float instead.
Filesize seems to be the same with "Half precision" checked or not.
Thanks
I'm not able to reproduce this one. If I enable 'Half precision' I've got a 16-bit float exr, and also the file size is smaller, as it supposed to be. Is there anything special in your scene? Can you reproduce the issue in a new simple scene as well?
Nothing strange I suppose...
Here a screenshot with AOV list, maybe cryptommate or something else not support 16bits?
Thanks for your fast response, incredible support (is Sunday! woow)
I don't think cryptomatte would influence this, but I'll give it a try tomorrow.
I've checked the code of the cryptomatte shader and indeed it disables half precision on the driver. So I recommend using a separate driver for the cryptomatte AOVs.
This will be fixed in an upcoming version of Cryptomatte. (Is still sets the driver to full precision, but modifies the non-cryptomatte outputs so they remain half precision).
I'm using Maya, I have the same problem. To follow @Peter Horvath recommendation
Is it possible to use 2 separate .exr driver in arnold, one with half precision "on"
and the other one without ?
Right now I am using two scenes instead.
I really appreciate any help you can provide.
In C4D is possible, only create another Render Driver and place Cryptomatte AOV there with "Half 16" check disable. In Maya I have no idea, but maybe is the same process...
