Hi JR,
GIF alpha is crappy anyway, because you have only one bit
(transparent/opaque) instead of the 256 levels possible in theory.
Especially for effects like glass you should use an 8-bit alpha channel.
Get the JDK 1.3 (RC2 was just released) and use the PNG format (1.3 rules
anyway). If this doesn't work I can send you a class written by me that
reads TGA images. When saving transparent PNGs from Photoshop, make sure
that the alpha data is in a separate "channel" and that you have a black
background layer.
And try these (not all at once, I think the first one should suffice):
appearance.setTransparencyAttributes(new
TransparencyAttributes(TransparencyAttributes.BLENDED,1.f));
renderingAttributes.setDepthBufferEnable(false);
textureAttr.setTextureMode(TextureAttributes.MODULATE);
Good luck,
-- Julian

Subject: [JAVA3D] texture with alpha channel
Hi,
I've tried applying a texture (gif) with alpha channel to a 0 depth Box
(cheap).
Also tried with a square index faced set.
Cannot seem to get the box to not render where alpha channel is 0.
(RenderingAttributes setAlpha Greater 0 ).
(trying for a decal on glass window).
Any hints? TIA.
