Help!

Hi all, going insane for two days… Ive got a height map imported and created a custom material from three textures but nothing is showing in the target layers of the landscape paint to paint with… any help will be amazing before i quit ! Ive tried making materials, material instances, vertex blend layers blend… non of them apply as a layer to my landscape paint … HELP

Just missed a step… Your Layer Blend nodes have"layer none" labels.
Select the LayerBlend nodes and give each layer a name. If it’s named default “none”, it won’t populate your layers list.
And both layer blend nodes need layers names.

OH MY LORD! thanks soooooo much @NotSoAccurateNo1 you are a legend !!!
