Looks like a deep dive into effects on
EOS might be in your future (unless you've done it now a month later).
Agreed, the reason for the error is that
effect is set up for
parameter(s) not on your fixtures. This kind of
effect is set up to work on specific parameters.
Stock Effect 910 "Color Smooth" is set up with the parameters for "
CMY" and "
RGB".
Didn't notice you mention the fixtures in use. But the advice above holds true.
The idea of color smooth is to
fade between parameters to create a "smooth" transition through colours and going into the below there are a lot of ways to emulate or customise it.
There are a few ways you can CREATE (or modify) an
effect to do this sort of thing...
1) Create a Step Based
effect to do your will.
2) Create an Absolute
effect using pallets/presets to do exactly what you want.
3) Create a Color or Linear
effect using parameters that will work with your fixtures.
There are lots of tutorials and guides available to do any of these (including the courses by
ETC) and doing so would greatly increase your skill and understanding of
EOS.
As well myself and others would be happy to give more information/instructions if you need further help. Highly recommend doing a quick search for the guides mentioned above.
