View Full Version : Rotating colour palettes - possible?

Hi All,
I am trying to make the colours in a gradient change with time.

I have a nice abstract picture, with a range of colours, applied via a gradient. And I want an effect like you get when those fractal pictures rotate the colour palette. Is this possible in LW?

Cheers,
Nick

how about using an envelope on the color channels, then use difference layers for textures to mix up the colors?

You could also texture it with a Quicktime. Which might be an option if your trying to simulate a fractal effect created in another app.

Toby, I don't see how you CAN apply an envelope on a colour channel of a gradient point - that is what I was trying to get at. The graph editor lets you do this for simple colours, but I cannot see how to set the RGB envelope for a point on a gradient.

I'm still on LW 7.5, in case that makes a difference...

Cheers,
Nick

no, you can't key gradients, I meant the channels of the base color, using layers set to 'difference' to add variation - you'd have to experiment, 'cuz I don't know what look you want.

Or you could just do the sensible thing and use an animated texture like riki said - it's what any studio would do, it's just not complicated enough for me :cool:

btw, anybody know what the heck this:

is supposed to mean/express?

I think that :o is meant to be a yawn!

But the Good news is that IFW textres supports the colour enveloping I want, and I am playing with it right now...

First render chugging out as an anim as I type!

Is that you, Nick?

Great to see you've got something going.
Mails been slow on yahoo so allow me to repeat it here:
No, not dumb at all: it ain't in there. And for what I'm speaking of, it's all in the IFW so lw versions don't matter.
This is one of the biggest requests I've seen, though; to have animatable lw gradients.

Nope, still talking about the IFW panel. All of them have a phase control for moving your color points left or right of center. I believe that if you do this small test, you will see what I mean:
- Open viper and make it itty bitty. - load a plane and fill the screen
- add the same IFW you've been working on onto the plane. Animate the phase from 0 to 1 to 0.
- Make a preview in viper.

I LOVE THIS METHOD for previewing IFW animation settings. Very easy to spot mistakes. Should be quite easy on the cpu. If you have a monster machine, the size of the viper screen can be increased to increase your joy. ;)

Oh, and in another thought I had, I have added it to the Texture World, as well, which alleviates the need for the plane. Hope that helps.

Later,
