| + | If the channel is part of a vector (this is determined by the last part of the channel name, i.e. .X/.Y/.Z, HPB or RGB), the output vector of the node will make the triplet of values available. | ||

| - | However, they have optional evaluation modes controlling how their values are retrieved if they are animated via an envelope: | ||

| + | There is a scalar and a vector output. Both will change their name depending on the selected channel. They will keep the existing connections though. | ||
