Procedural textures for eyes??

[pixel8]

Hi all

I've just learnt a method of creating pretty realistic eyes in Maya using a gradient and then layering procedural textures into each colour in the gradient....

I'm trying to apply this method in LW and wondering if it's possible....Can you apply procedural textures to each of the individual colours in the gradient?....

Or is there another method??

Thanks

Nope, this doesn't work like in Maya. You can recreate the effect by inserting different gradients in Alpha mode above your procedurals and connecting those gradients to a basic weightmap that defines the different areas of the eye.

Hey Mylenium

I thought that might be the case.....couldn't see any way to layer onto the colour channels of the gradient.

Not sure exactly what you mean...I'm pretty new to the whole texturing side of things.....

You've given me somewhere to start though....I'll have a play around and see how I go....

Cheers

Well, using gradients in alpha mode on top of other layers makes them act like masks. Since unlike in Maya they are not real textures but work as "remap ramps" you have to give them a parameter as input - in this case your weight map.

I just got the ifw textures plugins and they do an iris effect as a gradient procedural texture

they are at www.shaders.org

I havent tried it yet I just saw it in the pdf manual page 5

Hey Mylenium

That makes sense....I found some good info on weight maps so will have a read and play and see what I get....

Hey munky

Good call....I actually have those textures.....downloaded them ages ago and forgot I had them!....Will give them a whirl

Thanks for the replies

HI Pixel8,
You can use a gradient in the colour channel if you use the Distance from Pivot input.

That is put each eyeball in its own layer. Then Move the Pivot of the eyeballs to thier center.

Hope this helps

podrias generar los ojos con mapas proceduales usando ciclon!! (usando planar, dedes el frente)asi como alguos gradiantes y noise, pero te recomiendo mejor hacer un uv map,
y pintarlo en cualquier editor
