Jonathan beat me to it. I can confirm that what he says is indeed still
the case: textures and postage stamps use the same code path, which is
hardcoded to use the RGBA channels. There is no way to change this at
present; sorry.
It sounds like a good idea though, so I've added a feature request for
it. It's #17502 in our bug tracker.

Your typical GL texture methods like glGenTextures/glBindTexture() and any
texture setup/copying calls like glPixelStore/glTexImage2D.
The postagestamp system is what handles the texture creation and at the time
Nuke left DD it was hard-coded to use RGBA - I don't know of a current way to
change that through the DDImageAPI.

Hi,
I'd like to know what kind of GL commands are called by Iop::set_texturemap()?
cause I'm working with some EXR images, i am wondering if it's possible to set
a layer ( other than rgb layers) as a gl texture ??
And i don't want to use Shuffle to separate layers ;)
any response will be appreciated
Thanks
