We have been creating materials…"tree" let's say, from the "animator
clips" library, combining an opacity map (the tree, turned completely white
and saved as a cell) and a texture map (the same tree, as shown in the
original "animator clips" library). …so far, so good… but when we
apply this new material to a scaled cube (scaled to roughly match the shape
of the "tree"), and try to render this new object against a single color,
gradient, or other bitmap background, the opacity map does not seem to
work…i.e. the "tree" is there, but so is the cube! Note, the new object
is rendered as planned when rendered against another object…even a
background so long as the background is a "mapped object". Has anyone a
clue to what's going on here? Tag Grossman 73417,2322
Are you using 1.0 or 1.01 of 3DS? If it's 1.0, there's a minor opacity
mapping bug that inhibits backgrounds from showing through opacity maps if
RGB0,0,0 is used for the black areas of the opacity map. The fix is to use
RGB0,0,1.
This is probably your problem.
