Resolume Forum

I am trying to run Resolume and Chamsys together over artnet.

Resolume handles the video content and mapping whilst Chamsys drives some LED fixtures.

I have mapped Chamsys to the RGB add subtract effect so I can control the colour of both the lights and video easily.

The lights are on a slow fade and I would like the video to fade in and out with them, for me the obvious solution to this is mapping Chamsys to the layer opacity but it isn't very linear it seems to fade in over the first 50% with the biggest increment between 5% and 20% this doesn't seem very linear which doesn't match the fade on the lights .

Is there a better solution?

Try changing the dimmer curve on the chamsys channel you've mapped

Thanks for the pointer, that has made it a lot more usable.

When using Add as your blend mode, between 0 and 50%, the incoming layer will add intensity to the layer(s) underneath. Between 50 and 100, the layer(s) underneath will gradually cut their intensity. The exact curve depends on the content you are using for the incoming layer and the layer(s) underneath, but this is indeed not a linear curve.

For a 100% linear curve, you can use the Alpha blend mode.
