Rotating Stars problem
All right, here's my problem:

I create an AVS that uses Blitter Feedback, Roto Blitter, a Simple, and four pairs of rotating stars in four different colors.

THey show up as I create the AVS, but when I save it and reload it, only one set of stars appears!

Does anyone know why this is happening?

Rotating stars start at the same place every time. Since it's set on "replace" and nothing else, Only the last Rotating Stars appear (Try Set Render Blend - Additive, and see if it turns to white).

A good way around this is to make an SSC that mimics rotating stars... Not that it's easy...

Til then, you're stuck with being able to use 1 rotating stars.

Here's a superscope replacement:

Init:

offset=0;direction=-1;starsize=.2;pathsize=.5;©©©©©©©©;n=6;tpi=acos(-1)*2;t=offset*tpi

Beat: (empty)

Frame:

t=t-0.05*direction;af=w/h

Point:

r=i*tpi*2;x=cos(r-t)*starsize+cos(t)*pathsize;y=sin(r-t)*af*starsize+sin(t)*pathsize;

This only does one star, but you can copy the superscope. Offset specifies the initial position, in fractions of 2*pi. Direction specifies the direction of rotating (1 or -1). Starsize specifies the size of the star, pathsize the size of the circle they rotate on.

To have 3 stars in a circle, use offsets 0, 0.33333 and 0.66666. For 5, use offsets 0 0.2 0.4 0.6 0.8. Make sure you save and reload the preset to see their real positions.

...now if I could figure out how to get the stars to react to the music...

add "starsize=.2+abs(getosc(0,.1,0))*.2;" to the per frame
