3D gradient

[Godstrike]

Anyone have any idea how to create a 3D gradient in octane, I'm stumped!

See attached for a reference, the colour in the centre of the sphere needs to 1 colour and the outer 'mantle' needs to be another.

Thanks!

you have different ways to realize that. one is to build a sphere...clone them and use the multi color node.
another way is to use the octane gradient texture node
i can build a little video tutorial if you want

Hi, thanks for the reply.

I'm not building an earth, just used that as an example to illustrate the 3D nature of the gradient.

Essentially I have a large cloud of small objects that need to change from one colour to the other as they move closer to the centre of the spherical space.

I tried the octane gradient node, but couldn't find how to drive that kind of effect.

A screen shot of a texture node setup would be great:)

octane gradient is behaving like gradient map in photoshop, it changes the color of a texture according to the colours in the gradient.. it will never do a plain old gradient thing.. drive a noise map to a gradient map and then connect to diffuse and see.. try that with a texture

I don't know the Lightwave plugin but you should have the same nodes as in standalone.
Here is how to do it in standalone :

Many thanks! Will have to get to grips with the standalone for this shot:)
