How to extrude shape with sharp edges from curved surface?
I found that it is problem to extrude for instance cube like shape from sphere.
I tried different solutions:
1. after extrusion, add supporting edges to have that extrusion with sharp edges.
- this will break the shape of the object from which i did the extrusion
2. In Blender, add mean crease, mark edges as sharp and add edge split for sharp edges
- worked just in same cases, where the topology around where i did extrusion is relatively simple
3. Apply subdivision to make the model high poly and than use extrude tool
- this works, but the model becomes high poly, so it is hard to continue with modeling
4. Instead of extrusion, add separate object and assembly them so they looks like one piece
- probably not much real look, because for instance specular light will not be calculated
as if the model is REALLY one piece
Are there any other possible solutions, how to extrude hard surface from curved surface?
(simple case is extrude cube like shape from sphere shape).Thanks.
