Quote - Transparency maps are not transparency even are related.
A transparent object has a fixed value on how much it is transparent, a transparency map is a RGB image that modulates this transparency value, so it can turn the object more or less transparent by pixel value.
Strictly alpha maps are not the same as transparency maps, alpha maps only modulate the overall transparency for all colors. A transparent map can modulate each RGB component.
Poser only use alpha maps.

Ok, I don't think it helps to argue what exactly what does what and why. It just turns into a pissing contest. For the sake of this plugin, we're going with what Poser uses and that's an alpha map, ok? I don't care one wit how it does what it does or the difference between. The image used to calculate transparency on the leaves in my image was a plain old, run of the mill alpha map. Just black and white. And it converts to Lux just the way it should. That should be the end of it.
