Hi again,

Thanks guys, the different info cleared some things for me, but im still
running into some issues. Im trying to get the  it running like Ingo
mentioned, but by using Warp's vertex code. Which has been declared further
up, but i keep getting Float expected but vector or color expression found.
Kinda lost there. :(
Ive tried both of the point lines underneath here, since prisms need
coordinates to work. no luck.


prism {
linear_sweep
0,
1,
7,
<IP1>,<IP1>,<IP2>,<IP3>,<IP4>,<IP5>,<IP1>
//<P1,IP1>,<P1,IP1>,<P2,IP2>,<P3,IP3>,<P4,IP4>,<P5,IP5>,<P1,IP1>
pigment {Green}
}

Any more ideas?

Thanks in advance,
Chris.
