MakeTX and OSL AutoGamma?

So i just realized that my gamma looked kinda off and that made some of my diffuse colors look way brighter/less saturated than they should be.

Honestly when i build shaders i tend to leave autogamma checked for diffuse/hdr/ext maps and only untick it for files that represent vector or float data so that the gamma gets corrected to 1 when those maps are unchecked.

Shouldn't autogamma set the gamma for any exr, hdr or .tx file to 2.2 by default?

How does gamma correction with maketx get handled? Is there any way to prevent gamma correction with certain files by file type or file naming?

I'm not sure wether the second gamma correction that is causing the faulty color representation is actually caused by AutoGamma or MakeTX.

Auto Tx doesn't use the auto gamma setting
If you're running maketx yourself, then it depends on what flags you use (are you doing a color conversion?)

i'm actually only using the --oiio preset flag together with the -v flag

I select all files i want to convert at once and do so via sendto batch script

@for %%i in (%*) do "P:\Autodesk\3DS Max 2021\3ds Max 2021\ApplicationPlugins\MAXtoA\maketx.exe" --oiio -v %%i
