Remote control of effects settings.

Usage: Texture output (and input) to pass a scalar values etc to other effects in the routing.

Note that the codes were developed at a time when the effects typically only output 8-bit RGBA values. With Lightworks 14.5, higher precision can also be set.

Channel definitions

Transmitter

• Red and green color channel: Coded value to increase precision.

   float green = frac(original_value * 255.0);
   float red   = original_value - green / 255.0;
  

• Blue color channel: Status information

• Alpha channel: Uncoded original value (precision according to the GPU precision setting)

• Position of the RGBA signal in the texture: Depends on the remote control channel.
