Bump/Displacement tips for Seawater material

I need some tips about adding bump/displacement in Serengeti.

Is bumpmap the way to go for displacement in seawater material? I struggle with the settings. Where to change the displacement/bump value?

Hi Roy,

There is a special tool for actually displacing the rendermesh ( where bump mapping is faking the structure/texture by shading, displacingment is creating an actual rendermesh based on a texture)


Thanks Willem. I just found the dipslacement tab after posting but where to change the amount of displacement? Not sure about the settings

Hi Roy,

Black and White point are the amount fully black or white pixels in an image are being displaced from the base-surface.

And you might need to set the custom mesh for the object as Displacement uses that as base.

Here are two simple planes with the same displacement image added:

The only difference is that the one to the right has a custom rendermesh. (But do not set it too high).

Edit: And you need to toggle off the “Simple plane” option in the custom mesh setting.
