something about facing ratio too

what do you mean by 'in a particular direction', that could means lots of things

vague questions get vaque responses user added image




that's a "Ch" pronounced as a "K"

Like from left to right on a cylinder. Like a lightsaber switching on.

Nothing happens, when I mess around with the ramp and render it shows the flow of transparency. But in the actual scene nothing happens, nor does anything happen in a playblast.

Some things will only show up (or be transparent) in the render, but I'm not sure if this is one of those situations. Have you tried hitting 6 and 7 to see if the texture/lighting helps?

I don't think Maya likes to display transparency if done through a gradient, or any other type of texture, in the viewports.

As long as it works in the render you don't have anything to worry about..

cheers,

i'm pretty sure there is a setting somewhere that you can enable the alpha in hardware texturing, which makes it show up in the viewports
i just dont remember where such setting is.
i think i saw it on the gnomonology eyeball tutorial how you do it
