Video Sprites not flowing in flowfield

Can anybody please offer a little insight as to why my video sprites are not flowing into the flow field?

Could it be an alpha channel thing?

is it a luminance thing?

i'm running a black and white .mov at full HD resolution ...could that be why?

G-Force 3.9.4

Flowfields only react with Waveshapes and Particles. Sprites occupy the lowest layer and they don't react with Flowfields... ever (Possibly, because I believe, Sprites were originally implemented as static JPGs or PNGs or whatever. The whole Quicktime thing was an afterthought... Someone can correct me if I am wrong) They ARE colored with the least significant 64 locations of the current colormap.

interesting.... you said "They ARE colored with the least significant 64 locations of the current colormap."

Can you point me to a more elaborate explanation of this....I would like to know exactly how I should be making custom animations in after effects and how G-Force will output them.

thank you very much!

appreciated!

To be honest BTT is the resident Color Meister. I learned what I know by brut force.

The colormaps can be defined as txt files (*.map) of 256, 24 bit RGB values, or as a png formatted map. If locations 0-63 represents a 64 shade gray scale, the Sprite will display in B&W (or color tint). It is tough to guarantee the Sprite will be visible; the flowfields reacting from the Waveshape and Particle motion can totally obscure the bottom sprite layer. The professional license allows color PNG images to be displayed as the top layer... An example is the GF startup splash screen.

the file 'C:\Program Files (x86)\SoundSpectrum\G-Force\ColorMaps\ColorWheel.txt' provides some notes

I have the Platinum edition. I can't find where to set this.

this is how it used to be, when naming the file you would put ~ in the title to
make it show in the foreground.

ex, moonglow~.jpg

things may have changed but try it anyway it may help.

ps. jerohm can definately tell you what to do.

Now....how do i make it react to sound? I saw a post about it but it was very technical and didn't show any exact formulas but it used the fft(s) call in the default sprites file.

O kno i'm asking alot.... but while i'm having my cake!

thanks again!

That never came about and i doubt it can be done
