Here's an interesting problem. I am trying to use multiple planes (or any
kind of shape for that matter) where all of them rely upon masked textures
so as to ensure that their surface is partially transparent.
However, in the following example even though both gridshape objects (patch
guts borrowed from another example provided on the listserve) are
transparent, only one of them is truly transparent, while other is only
transparent in respect to the background color.
If you change both shapes' z-axis, you'll find out that one of them is not
really transparent but only blended with the background color. The desired
goal is to have (in this case) both of them truly transparent both in
respect to background and to each other.
FWIW, adding more shapes perpetuates the problem with all but one shape
being partially transparent only in respect to the background.
Any ideas how to address this?
