landscape texture blending problem.

Hi Everyone,

I have a question about multi-layer brushes in UE4.

When I try to paint with a layered brush there is no blending at all.

In the tutorials online I see people paint grass texture in to gravel textures simply by painting over them with a feathered brush.

When I do this, I overwrite the previous texture completely, regardless of how feathered my brush is.

Is there a setting somewhere I’m missing?

Has anyone else encountered this?

Cheers
