Passes the input of one of its connected inputs through, acting like an exclusive switch.

All Parameters Local variables Example files

This COP passes the input of one of its connected inputs through, acting like an exclusive switch. It does not use any image cache space, nor does it cook anything.

Note

If the Input Index parameter is animated, the all input sequences must be identical in the following aspects: resolution, planes, data format, and frame range. If you require that they differ, please use a Blend COP instead with an integer blend factor. If the Input Index is not animated, the input sequences do not need to match.

Parameters

Input Index

The index of the input to pass through.
