Brightness shader with transparency


How can I manipulate a BAM or something so that it acts more or less like the Brightness shader with brightness set to 0, but with transparency? It’s for “billboards.”

The brightness shader just adds white multiplied by the brightness number…and the color is not lit. So you just need to put your texture in the luminance channel, change diffuse to black, turn off the highlight shader and you’re done.
