Exactly 80, or more than 80?
While I'm at it;
Any Ideas why?
80 - In Blender Icosphere - subdivision 2 = 80 faces
It would depend on the export type and import into Blender. Basically it is finding the texture image but not the image for the uv. If it is a problem you can use Accutrans
http://www.micromouse.ca/ to convert to collada and then import.
For Blender Freespace stuff I usually don't bother with applying materials.
In edit mode hit the A key to select all faces.
Set up a split window with the 2nd one set to UV/ImageEditor.
In the UV window hit A again so all the uv stuff is selected. Then image> load and choose your image.
