Replace CHOP

From TouchDesigner 099 Wiki


The Replace CHOP can be used to replace channels very quickly. The output of channels in Input1 will be replaced by channels found in Input2 if a matching channel exists in Input2. Any channels that are in Input1 and not in Input2 will be output without being replaced.

You can also use this to quickly delete channels (this method can be faster than the Delete CHOP). To do this send all the channels to Input2, then send the channels you want to keep to Input1.
