vector displacement neutral colour

[stevesideas]

I'm currently using the phoenix ocean displacement map to control the displacement on a plane. I would like to be able to mix a noise pattern in with this so I can have some areas of smaller or no displacement. Does anyone know what RGB value I should be using to obtain this neutral colour for 0 vector displacement ?

Would it be the green/yellow colour of this image ?

R 0.5, G 0.5 and B is the amount or magnitude. Not 100% sure on that one.

So in this case B 0.0

So vector is measured using float ? I guess it would be the same as 128, 128,0

Thanks

It's the same, yes.
