Hello Espér,
Thank you for your answer and helping me out. I will certainly look into the manual as you have directed.
I looked into the wiki and have downloaded the "Particle Effect Builder" to try out the program. It appears that the other particle editor - "Easy Particle 3.1 Editor" is not available anymore, since the website
http://www.easyparticle.de/ is down.
You said - ".......... GS can´t handle Frame-Animations of a GIF"
Can GS handle other file formats like say - PNG, TGA, TIF etc. ?
And can GS stream video files (AVI, MPG, MOV, FLV) on 3D mesh surfaces / textures ?
Thanks,
