I am trying to UV unwrap a pear shape object I modeled with an image of a pear. I just want a semi-accurate projection of the image onto the object (Not trying to make this look lifelike). The unwrap mode "project from view" seemed the closest to the image in terms of shape, but the texture is not showing up at all on the object.
Work through a camera view that is set to use the same render pixels as your reference image texture, and unwrap 'Project From View' through the camera view. Then your texture will align correctly to the uv projection, and if you plug that image into your material then it will show when in Texture view. If you don't want to do that, you can set up Proportional Edit with the O key in the Uv editor and select single verts and drag them around to match the boundary of your pear image manually. Mistake I see in your picture is that you have the node window set to Compositor,and not Material and I cannot see if you already mention the image as a texture in your material to tell.
