is it possible to unwrap an Icosphere in blender? well first of all , I need a triangulated mesh for an externa aplication, so I decided to use an Icosphere an export it then , however I noticed something ugly with Icosphere ... I would like to know if I could unwrap an Icosphere, here in blender.
I am not satisfied with "cylindrical proyecction"  and even with "smart UV" for triangulated mesh in this case, consider that icosphere is a triangulated mesh. I do not need quads  , trust me , I need an Icosphere and a well unwrap process. 
what  tools should I use to get a nice stretching with UV sphere?
 see this picture, is my best efford...but I am not sure ..


can you see it is an option called "generated UV's" in the "add ico sphere panel"... also there is subdivisions levels , size ...  I checked "generate uvs" and that is the result.... but this is not a good uvmapping process... I mean I would like to get NxN size of UV and aligned stretching... is it possible with triangles mesh as it??
You will need to mark some seams. Ctrl + E, Mark Seam (and inversely Clear Seam)

An easy seam is one continuous seam around the sphere, which gives a good UV map when unwrapped.




Another seam type...
