[Material/Skin Thread] Laser Textures?

(Since the subforum’s title is “Models and Skins”, I’m posting my material thread here. If it’s an issue, admins, please move it to the proper forum)

How would I go about making a laser effect for a SWEP? Are there dimensions I have to follow? Where do I save it to? Should it be horizontal or vertical? Does the VTF need an accompanying VMT? I’ve searched for it, and I have found nothing.

Lazer?

Define what you mean, like a glowing lit up part on a gun or what?

A beam. Like the rope textures. Let’s just say another rope texture.
