Searched about. Not very encouraging. The Rebed site (rebed.cjb.com) is down and the only email I found was revolution@workmail.com. I sent a message but it ain't very encouraging.
I find it hard to work with splines but i am trying to learn to use them. ONe of my (many) side-projects is to model a Lightsaber using only splines. Shouldn't be very hard.
Okay so i did a little seaching on google and found this: A Galaxy Sizer A Refined Material Generator An Ingame Editor(I think you need to uninstall RebEd to use this program) I haven't had time to test these. PLease tell me what you think.
