Using VEX to read/write parameters values April 29, 2019, 10:28 a.m.

Actually after studying what I'm trying to do carefully I just realized what I'm trying to do is pointless and I wouldn't even need the dot formula that's in the manual….all I have to do to solve my problem is to create a blank channel parameter in the wrangle node and just copy it …..then just use copy by reference on any parameter that want to control…and make sure that the channel parameter I created matches the data type,….Int,float,….I don't think creating a vector be needed….unless you wanted to create a parameter with x, y, z,….but in all this is still pointless….just drop a null node and reference every parameter that you want to control
