I have a COB fixture that is only capable of white color adjustment from 2800k - 5600k. Fixture editor doesn’t have a white color channel assignment. I know I can use a custom color mix assignment. However, I cant use HSV or CMY sliders for that.

Is there a way to make a fixture profile to adjust white color temp without having to utilize the custom features tab?

Color temparature does not form part of Vista’s generic fixture model. “custom color” is the only way to acheive it. (You could add the K ranges to the DMX profile though).
