Hello, absolute beginner here
I’m thinking about buying this bundle of textures: Stylized Magmaland Materials | 2D Textures & Materials | Unity Asset Store
I was wondering, if I apply those textures to a perfect sphere (the Unity GameObject), will it have the cracks, the little hills, and the bumps like the objects shown in the demo images ? Or do I have to model an object in blender or such and add manually all those details so it fits the texture ?
Thank you guys !
No it should work on a perfect sphere, because as I can see the normal maps are already included in it. Still if it doesnt work you can always watch this video.
Still normals don’t always look as good as the real thing. But are good for Performance.
Hello, thank you for your reply. I tried what you said, yet it looks still like a perfect sphere, it’s nowhere near the screenshot in the example. Also, I played the sample scene and again, it’s very flat, especially on cubes. But well, I guess it still gives a slight impression of depth 
Hello. 
What material/shader, were you using?
It kinda looks like the outline of the spheres is perturbed, which would be more than normal maps. Normal maps create additional detail in the lighting without affecting the underlying mesh. To actually affect the underlying mesh, you’d need displacement maps.
If you have any particular questions pertaining to an asset package in the Unity Asset Store, it is always best to first check with the author of that asset. Each asset always has contact information for the author. The only exception I can think of is Unity’s free assets. Your question sounds perfect when directed to the author, others are speculating although I think @jhocking is correct.
If you look in the package contents, there are textures called “height” and “roughness”; I’m guessing one of those is a displacement map. But as @Bill_Martini points out, this is just speculation when you could contact the author directly.
The height map is used as a displacement map. Does the Unity standard shader support displacement? Only google knows.
