    Sliders handling expressions??

    Hi,

    I'm working on a lighting rig, where i want to adjust the whole thing with few sliders, who then controls several properties of several items at the same time.

    Simple example of how i want a typical slider to work:

    When slider is at 0:
    Light A at maximum intensity
    Light B at minimum intensity

    When slider is at 1:
    Light A at minimum intensity
    Light B at maximum intensity

    Im only using 2 lightsources on this example, but ultimatly i would love to control XX lightsources.

    Is this possible?

    No need to panic! I found this:

    Let's see if this does the trick...

    I'm having another problem - it doesn't seem like LW allows me to assign more than one expression on each channel.

    Ie. i cant do this:

    Slider A alters light intensity on light 1-5 - all lightsources are changed relatively.

    Slider B increases intensity of key/sun light, while lowering the value for the rest.

    The setup for these sliders are controlled by expressions, but only one slider works, unless i use alternative channels for the light (wich im doing right now (using falloff range as intensity channel, but this is a crappy way of doing it, and besides the light changes dont show up in OpenGL)), but i can't continue like this, since i need to control same channels with multiple sliders.

    Any ideas on how to accomplish this?
