Hi there
I can't remember the cog verbs nor flags off the top of my head, but is the effect you're after, something similar to what happens when you drop a Sequencer Charge (top mat flashes red)? If so, then I remember seeing the verbs somewhere in the weap_seq.cog file I think....
Personally, I'm sure there is a way of scrolling a texture across a surface, but I just don't have the DataMaster at hand to look up any ideas...
Hope this gives you some ideas...
