4 Sphere models with perfectly Quad Topology. Unwrapped specifically for purpose of material presentations with displacement or height map ( for example Substance materials in Marmoset Toolbag ).
As you see in above Marmoset renders, displacement works perfectly . however please note behind the sphere there are visible seams - This is a necessary compromise in order to make it work from front or three quarter views.
This unwrap is not suitable if you plan to rotate around the sphere and show it from all angels ( not a good unwrap for a planet for example ). Geometry itself can be utilized for wide variety of usages. For example sculpting or when you need a quad sphere without poles.
For convenience and saving time, 4 density is included in FBX & OBJ formats: Quad Sphere 3k Quad Sphere 12k Quad Sphere 46k Quad Sphere 185k
Each density is a seperate file so you can easily drag and drop any of desired spheres into your viewport.
