I made some models in blender and finally transferred them to unity...i see them in the project folder but cant see them when i drag them into scene...please help
Maybe you just need to zoom/focus into model by pressing "f"? Or try importing with different global scales.
Which version of Blender? I assume these are .blend files? I've had pretty good luck exporting as Collada 1.4 from Blender. Make sure all the textures and so forth are within your Assets folder somewhere.
