I mentioned that on line 2, that there is no 32bit float. And I just mistook TG for having such a common format in DCC.
That's where I'm just like "Meh" with some of the logic put into TG. It's backwards. EXR is a waste when it's not even utilizing the standard method of use, incorporating channel information, etc, in one file.
And then we don't have 32bit float TIFF, which would be the proper exporting method here, since we are not utilizing the standard workflow of EXR.
Also stranger yet we have a reader that can read 32bit float TIFF, but not write it.
