I'm trying to create a cylinder with a logo design upon its surface.
I've created the logo in GIMP and its in PNG format. At this point I have
two problems:
1) For the life of me, I can't get a PNG into POV that has a transparent
background. I want the logo to be over the top of a (POV) textured
cylinder. What settings should i use to get a Transparent PNG (or GIF, or
?).
2) The image that is mapped to the cylinder "reflects" onto the far side of
the cylinder. This creates problems when i try to scale the image to the
approprate size, as the two images (primary and reflection) smear each
other. How do I make it not reflect?
You can see what I'm talking about here:

Here is the code for the flag object:
#declare motorLabel = cylinder {
<0,0,0> <(2*3),0,0>, (2*(bodyRadius+0.0001))
pigment {
image_map {
png "flagTestTrans.png"
map_type 0
once
}
scale 0.5
}
rotate <-80,0,0>
translate <1.25,0,0>
}
