Surfaces to different heightfields

[Mid-Knight Acchan]

To the dear users.
I want to color different heightfield and the whole of the planet.
At present, the color of the base passes away.
What will I make a mistake in?

If you mask both surface layers by the respective areas of the heightfields, you'd have the base color again.

By linking Heightfield to the child terminal at the surface, the separate colors could be put.

However, when doing advanced limitation and inclination limitation by the surface layer node, it doesn't work successfully, being connected.
Will there be an other way?

This is a better way.
