#Overlaying Animations
3 messages in this thread
I did'nt really explain myself enough Jack.
I dont want to use video post. Eg. I have a bitmap of the stars at night. I
have four small animations of space ships which don't move but you can see the
thrusters burning (animating). I want to overlay the space ships onto the BMP
and then move them via some program code. This effect will give me the
availability to randomly place the animations on the BMP. The problem is that
the ships background is black, I want it to be transparent so that the ships
and the BMP look part of one animation.
I also want to randomly change the BMP to different star scenes.
A bit like the After Dark screen savers for windows.
Thanks
Geoff
Hi Geoff,

It seems that you need to read pg 7-210 in the 3ds ref man for an understanding
of Render-Alpha. A flic animation file doesn't contain alpha data. Please also
see tutorial 22 for further insights to the alpha channel and compositing
techniques.

As Jonas said, you need alpha to properly composite something like that, and
flics don't have alpha. You'd be better off making Targa frames with alpha, and
programatically flipping through them while positioning them over your bitmap.
(Presumably, you're planning on programming your own compositing system as
well?)
