I've got a dozen or so WwCw fixtures I'm pixel mapping. They seem to only respond to address mapping and not fixture mapping. My only thought is the engine doesn't know how to reference the Ww and Cw channels as they aren't real colors or associated with anything. I really just want it to control the virtual intensity and let me mix the colors on the desk. My work around right now is two identical pixelmaps for their addresses and then reference them the same except using their intensity as their temperature adjustment. Fairly annoying. I swear I've done this before so if there's some brain fart I'm having let me know.
These are LED hybrid litemat 2, driven through 4x4 e-control led direct dimmers.
