    Hey,

    I was wondering why in quickshow, you can use the "Relative Power" slider in the static beams window to smoothly fade the brightness of a TTL laser up and down however when trying to use the "Brightness" control in the beam attenuate window, its either on or off?

    Why not be able to use the relative power setting when using fade in/out fx?

    Am i missing something?

    TTL lasers only know two states, On and Off. 100% and 0%.

    Try your lasers on analog modulation, If your laser is able to do Analog modulation, use that to get brightness control.

    Hi bob, thanks for your reply.

    I understand this however what I don’t understand is when using the relative power slider, I can make the laser fade in and out smoothly, how does that work?

    Many thanks

    By changing the amount of points that are projected on the same location.
