Passes: Export in EXR 16 bits foating point option?

Hi all,
There is an option in the Standalone to export passes to OpenEXR in 16bits floating point. I dont find this option in the Octane passes in Cinema 4D. Does Aoktar forgot to add this option in Cinema 4D or do i need to buy new glasses?
I ask this because I'm starting to work with Affinity Photo that does not support well OpenEXR exports without this option. Exports from Standalone work very well with this option.
EDIT: Of course i've seen the Depth option... But the 16bits/channel doesn't give the same result like the similar Standalone option. With this option from C4D, all channels RVB come as separate layers in Affinity Photo...
Thank you in advance for your help.

What's problem with "Photo"? I'm an user of it also. I don't use Octane SDK functions for saving exr,etc.. I'm setting 16/32 bit flags for saving the EXR as you set in interface..

Thanks for your answer aoktar.
Here screen captures of the results from Cinema 4D and Standalone in layer tab of Affinity Photo. As you can see, the result from Cinema 4D isn't the same.
Well... It's not very important because .psd or .tiff works fine but the files are really heavier.
I hope these informations will be usefull.

- From Standalone to Affinity Photo

- From Cinema 4D to Affinity Photo

Yes i notified these seperated channels. I'll make tests why happen.

EDIT: Since i'm using c4d functions it happens same as C4D's EXR saving results. Did you checked C4D's own EXR outputs in Photo? I can't get it as we wished.

Hi Aoktar,
Thanks for your answers.
I've tested right now every OpenEXR file formats from Cinema 4D visualizer "Save as" dialog. None is supported by Affinity Photo. With so much file formats unsupported by Affinity, i probably should go to the Affinity support and not the Octane support...
In my tests, i've seen also that .tif 32 bits isn't well supported too. The save from Octane passes dialog gives a flatten picture without layers and the save from C4D passes gives a file without the Beauty pass (when i ask it in Octane passes dialog). For comparison, i've opened my .tif tests with my old Photoshop CS5.5 and results are the same. The same too for 16 bits and 8 bits. But curiously the files are well opened by the Cinema 4D visualizer. Then there is a problem with standard .tif format with old Photoshop and Affinity Photo but not C4D visualizer.
FYI, if i make a "save as" of the tiff file opened in the visualizer to another tiff file, i'm able to open it correctly with layers in Affinity Photo and old Photoshop.
As i already said, .psd is well supported by Affinity Photo and my old Photoshop, then it's not really important for me. Just details but it's good to know.

FYI, the problem with OpenEXR and Cinema 4D is known:
