SpotLighting

Quick question - remember I know nothing about 3D lol

need to lightup a specific section of a 3d cylinder. Do I use a sprite and alpha it with a bright white, or can I use a lightsource as I've had limited success doing it that way :)

using the normal lights doesn't work very well unless you have a high detailed model. you could multitexture your model. first put the orginal texture on then put a spotlight texture on (remember and clamp the UV co-ords) are move it to your desired area.

hope some of that helped :D
