this will be hugely helpful for doing multi-plate compositing work in Sony Vegas. Vegas handles transparency so much better when it's integrated into the same file as the RGB data, e.g. the way PNGs do it. i'll try and remember to post a test video once bug #098-039 is fixed.
Raxx:
Hm, is it just me, or do PNG images load inverted as textures?
ronaldefarmer:
Captaindrewi and Crashdrive: The PNG texture seems to work very well for me, aside from being inverted. Here is an AN8 that I made in 1118, along with the PNG texture.
It doesn't seem to work very well in the viewer though.
Steve:
ronaldefarmer: Transparency for lights is a great idea but it's not that easy. I've wanted to support that for a long time. Adding it to the ART ray-tracer is the most straightforward, and then probably the scanline renderer but only for ray-traced shadows. OpenGL is considerably more difficult.
raxx: I think I know what's happening with the inverted output. Windows and OpenGL disagree on whether the top or bottom row of pixels is #0 so I do a bit of flipping of images. I think I'm flipping the .png output when I shouldn't be. I have some investigation to do to make sure that I'm not just moving the problem around but I'm sure I'll get it fixed :-)
CrashDrive: I think I broke the transparency texture in the OpenGL views. It does seem to make the material vanish. I'm looking into it.
#098-038 - OpenGL transparency textures don't show
ronaldefarmer: Your example works in the viewer for me, alpha and all, but I can't tell if the alpha falls off smoothly at the edges or abruptly. (And thanks for the compliment :-)

Couple of Animated renders using Png transparency First one with ART other with OGL
