Material doesn't appears properly I have a material which looks pretty cool in the preview window however after applying it to an object, it isn't the same the material's preview is. How can I made my object to look same way the preview's object does? Sorry I am a new in Blender so I don't know how to google this problem. I tried find a solution but nothing found.

Here is reference to the file, the file is too big (80mb) for blend-exchange.giantcowfilms.com
And here is reference to the original material in case it helps. A tried the author's recommendations (enable Experimental mode and Subdivision Surface) but that didn't help.
Thank you in advance!
The material uses a displacement and will work only with Cycles rendering.
Also, the displacement scale is relatively low.
So, use Cycles and increase the displacement scale (check all parts in green below):

Additionally, you may need to add some subdivision to the object for a better rendering of this displacement.
