question about plugin use


i have a question about the legimate use of plugins available. how far does the righful use of plugins go?

let me give an example there is the l-system which allows the user to create trees and bushes. Am i allowed to use trees i make with it in another enigne like a mod for the hl2 engine or is that prohibited or is that ok when poper credit s given?

thx in advance

The author of the L-System GUI:

makes no mention of any liscense and there is none included in the .zip. To be safe (and decent) just email him for permission and if you get no reply credit him in your game and you should be safe. As long as you only publish what you produce with the script (and not the script itself) then the copyright is yours unless stated to the contrary in some liscense agreement.
