Store reflection map in Green channel

asdaq

Hi,

It might be a noob technical question but I am coming from the art department and trying to approach more technical side as well.

So my question is: How can I create the texture .tiff file where there will be information only in G channel and the rest will be clean?

I guess it might be one line answer but still all I managed to google out - didn't work.

Why does it need to be green channel (if the rest is going to be clear)? Can't you just use greyscale?



Just deselct (in Gimp /Photoshop) green and alpha channel in channels (should be next to layers) and delete everything. That way you end up with 1 greyscale in green channel and 2 unused ones.

Thanks for the info. I figured it out myslef as well.
The G channel wasn't a specific choice - rather an example.

This is often called "channel packing". Some examples here FWIW
