i hope my post is right here:
I found this:
http://realitychess.altervista.org/physics/ (The Marble thing)

i get the demo to work and i can change the size of the BALL with milkshape and actor studio.
But what worldedditor can i use to make maps for that?
the rfedit and rfeditpro seems not to work. May be there is a little more info for me!?
I love games like that, i am also the founder of http://www.q3geoball.quakeit.de but we have no physics

I want to make a puzzle game with the RF engine.... push some boxes.... building bridges... etc.
Like Marble Madness Gold or Ballance. But for that i need more info to make levels for the Marble sample.
Anybody?
May be somebody is interested to work with me? Feel free to get in contact with me.
Thx for reading my 1. post
