The waterfall material is essentially a 2D "moving texture" effect that uses the slope angle of a user-imported model to set the foam texture speed, direction and opacity.

If you place objects in the water, 2D foam will form along the intersection lines (see the sphere on the rendering below).

There are 4 types of water in Lumion Ultimate.
Lumion Free only gives you access to the first 3:

1) Water planes (in the Landscape section)
Water planes do not include foam.

2) Ocean
The Ocean does include foam, but it is a function of the "Wave intensity" slider.

3) Water material
The Water material includes a foam slider. Import a flat plane and assign the material to it.

4) Waterfall material
The Waterfall material includes a foam slider.

So you don't see any foam at all along the lines where the plane with the Water material intersects your logo and the terrain?

The foam amount depends on distance from the water to the object, ie, scale, so if your logo is very large, the foam will be an exceedingly narrow strip.

Can you zip and upload the 2 scene files and the logo files please?

Yes, for some reason foam tends to get less opaque in the shade. No idea why though
