Hey guys this is my first time posting on the crydev forums, So I was wondering if anyone knows if it possible to use the blend layer to have bricks show on a concrete mesh, kinda like in the picture
. I thought about trying to do it with decals, but I dont know if I would be able to fake the depth better if I used a blend layer. Thank you.

Yes if you want accurate details you need heightmap of you main texture (for example bricks). Fortunetly the heightmap do not have to be super accurate (of better hm will yield better results), but one genrated from let say CrazyBump will be enough. Remember to Vertex Paint your meshes, or Blend Shader results will look very bad. So for each unique texture you need unique material.
Of course you can reuse same material on every mesh if it fits.
And no. You can use generic Perlin Noise map. It will work fine for more flat surfaces, like plasters, tight bricks and so on. You can reuse it as much as you want.
Regadless of above Blend Shader loose a lot of it power because we can't paint vertex alpha directly in snadbox for more unique look.
