Capture Scene on Movement

When enabled, the Respill scene capture will automatically update on plane movement.

Note: This decreases performance while plane is moving

Backplane Enabled

"Backplane" is geometry placed just behind the video plane, which can cast shadows and might be necessary for certain effects.

Try to avoid using it, as it can cause issues with DOF and AO

Backplane Alpha Threshold

Try to Fix Antialiasing Edge

This smoothens the edge of the video on the compositing plane. Try disabling it when you are

  • not using the video keyer

  • using multiple compositing planes

  • OR there is nothing in front of the compositing plane
