If you right click on it, is one of the options available Edit RGB Blend?
I talked to superman on the Australian forum. He is using nutcracker effects with lsp.
(Warning, i know nothing about LSP).
he has 16 strings of 50 rgb pixels. This would be 32 strands of 25. He tried that model and ran into all the problems you are seeing.
He said that when he imports Nutcracker (he has an 800 pixel tree, 2400 channels), they come in as separate channels. If you combine them, they turn white instead of the real color.
Here is how he fixed it.
He modeled his tree in nutcracker as one string with 800 pixels. He folded into 32 strands.
His real hardware is 16 strings of 50 pixels.
He created his model as 1x800 ( didnt know i supported this, boy i am good)
Generate effects and get an lms file.
He imports this into one LSP
He opens a second LSP that has his real sequence. I think he said it cut and pasted it and selected something as the controller, blah, blah. i dont know the screens he was referring to.
When he was all done, Nutcracker effects in LSP!
I have asked him to make a tutorial so i can post it. He said most people in Australia use LSP not Vixen. Maybe this method can give people some stress release that they in fact can get Nutcracker into LSP.
I still plan on making a native msq file. I expect that is at least 2-4 man weeks of effort. Expect it in jul/aug time frame unless i run into something unknown (Like my work load at Oracle).
thanks
