similar real-displacement-textures

we all know about rdt’s amazing texture packs. i want to know if there are any other texture packs like rdt.

There are few scattered over Gumroad. ( Tutorial - Forest Ground Complete Package )

And now on textures.com too. ( Textures for 3D, graphic design and Photoshop! ). These are damn precise, but quite costly with the new membership system in place..

And than there is (‘will be’ ) Megascans ;- ). Without breaking any anything, it will be pure madness.

I bought the pure polygon winter ground pack. Looks very good on unreal engine landscape!!! Also going to use it to learn substance designer eventually.
