Landscape material with atlas

I’m trying to import terrain from other engine and successfully import heightmap and splatmaps. I have trouble with making material for landscape for 8 textures because of texture samplers limit (16). I know that using atlases with 4 textures in each is the right way, but don’t know how to split atlas at material. May be anybody already solve this problem?
Thanks in advance.
