alpha issues with EXRs used in a constant shader

["Benjamin Huber" <bhuber(at)ilm.com>]

hi all,

i'm using an EXR plugged into the colour channel of a constant shader. the EXR has no alpha. however, doing a render region and toggling between alpha and RGB shows that the RGB luminance is being used as alpha.

i have no idea why, but i don't think it should be like that. other shaders don't behave like that.

any ideas? i have a sample scene but it's kinda big (300k) - if anyone wants to fiddle around with it - let me know.

thanks!

-ben
