This tutorial explains how to make a shader that blend object with the ground by extracting the ground texture and applying it to the object. Here is an exemple:
I would like to use it in combination with a displacement modifier to increase realism. Turns out the gradient along the Z axis is not affected by the displacement (he remain straight) as you can see.
Is there a way to get this gradient affected by the displacement map in order to achieve a nice blend between ground and object (blend follows geometry) or any other solution to get a nice blend with an uneven ground, some geometry node maybe ?
