Octane Gradient Texture

[sampakinpa]

Hi,
Can someone explain how to setup an octaneGradientTexture node for making a gradient texture from one color to another like the maya ramp texture?

[zboog]

I'd be interested in knowing this as well, because I messed around with it recently and ended up just using gradient file images because the Octane gradient texture didn't seem to work as I expected (like the Maya ramp).

The octaneGradientTexture is not a ramp texture.
It take the luminance value of the input texture, and remap the black and white value white the selected color.

You can use it to create a ramp style gradient if you connect it to a (cosine) mix texture.

[sampakinpa]

Can you give us an example of the connection order to achieve that?

[p3taoctane]

The cosine has two inputs in textures .. what does the cosine mix connect to ... the diffuse?

I can't seem it to work?

Appreciate any help

Sorry I was mistaken it works a little different than I remembered.

You can however stil get a ramp like effect using the gradient texture. Just connect a sawtooth / triangle or sine wave to the input. If you place a colorCorrect in between you can even adjust the transition by changing gamma.

Cool, cheers for the info.

Thanks that is a big help
