I got the burning and electrocuting images, so I noticed they are exactly 16 shots in one image, kind of like stopmotion thing, so anyone knows how to make this images work in game?, would be very interesting do this kind of thing

In asset manager
material type effect/ surfacetype none
Columns 4 Rows 4
Blendfunc add (for fire/electricty fx)
At the bottom select "no fog".
Then in fx editor open an fx (fx_glow_hanginglamp). Select an element (glow) duplicate it, in the visual tab load your material from raw/materials and remove the original. Then set the fps to 16 and "indexed" and press play.

In the script what I should do?

Use playfx or playfxontag depending on what the fx are doing.

Of course, thanks a lot for the help, can you help me in the "Lens Effect" thread?
