Increase your surface resolution (by subdivision) for a better displacement display.

Since its procedural materials, some special effects like moisture and water dripping were added to the wall materials. If you want to rotate the evolutive materials, please rotate the UV's instead. 

Yes, you can also try to change the texture coordinate for other result !

Due to the complexity of the procedural process, we advice you to use the Evolutive Materials with Cycles Engine. 

The displacement is not currently supported by Eevee Engine . A bump version of each material was added to fix this problem and increase the render realism.

Actually, the evolutive materials are made for plane surface . You just need to subdivide a simple plane and add a subdivision modifier to see the magic happen !
