Thanks Zy, I found those earlier <img src="smileys/smiley1.gif" border="0" align="middle" />
The first link has dead downloads. The second looks great, but doesn't explain how to get the effects working. I'm wondering if there's some particular way the textures need to be saved, using specific colours or transparency... or something.
Whenever I try to use the Plasma effect, either nothing is visible at all, only a small corner is visible, or the whole thing is visible but flashes around when the player moves. It varies based on the size of the plasma box.
I'm probably missing something simple, which is why I would love a tutorial that explains how to use the feature. All I can find are examples of what can be done with it, but not how to actually use it. I want to create my own textures and effects rather than copy/paste someone else's <img src="smileys/smiley5.gif" border="0" align="middle" />
