<<That's my question as well. Those Alpha Channel buttons in the Yost IPAS
Boutique #1 .IXPs (Flare, Hilite, Glow, Blur, etc.) appear to be utterly
useless. Here's why: the instructions SAY that they will look at the Alpha
Channel of the item above them in the Video Post queue, assuming that said item
is 32-bit (has an Alpha channel) and that Use Alpha is On. This is apparently
not the case. Apparently they instead look at the ACCUMULATED Alpha of ALL the
Video Post queue entries above the .IXP entry whose timelines overlap at that
frame. In other words, they look at the Alpha channel of the CURRENT
COMPOSITED IMAGE being built, as it has been composited through the various
layers!>>
That's my question as well. I am waiting for this problem to be corrected in
R.4 of 3D-STUDIO,
but for the time being, untill there will be any upgrade to Disk-1, we can't do
a thing with it!!!
Thank you very much for the long reply.
Sus.
