OpacityPP turns black when negative

[Anonymous]

Hey guys, is there anyway to have opacityPP turn transparent instead of it turning black?
I made a kill expression when opacity < 0, but after that I can't work with my opacityPP in creation - seems really weird..

Hi!

Simplified:

Color * Opacity = final display value

White * 1 = White

White * 0.5 = White (50% of Color transparent)

White * 0 = nothing to display (100% of Color transparent)

White * -1 = Black

Red * -1 = Teal

"I made a kill expression when opacity < 0, but after that I can't work with my opacityPP in creation - seems really weird.."

This works (Maya 2017 update 3)

Thanks - helped me understand it better and I figured out a way around it 😄

Hi!

Also set Evaluation Mode to "DG" and not "Parallel" when doing FX / simulations in Maya, or some things will not work correct.
