If you want multiple POM layers, you need to do the parallax for each layer using its own heightmap. Technically even the alpha needs to have parallax to be correct but it is impossible to do that for landscape layers. In general as long as the base alpha is somewhat blurry that part should not be noticeable.


The custom nodes on the left are simple "SampleGrad" nodes that fix some bad mips from sampling with parallax UVs.
The code for that node is:

return Tex.SampleGrad(TexSampler,UV,InDDX,InDDY)
