3d texture mapping in photoshop

[Lumi 8]

  Hello can anyone help,

1.Is it possible to mesh a photograph onto a 3D shape in photoshop without getting blur on edges?

2. Do you have to render it out if no scene (only solid colour) is being  used as a background.

I have only found info/tutorial on using  textures created in photoshop rather than a photograph. Do I have to take intial steps to prepare the photograph first?

Any help would be appreciated

I would think a lot would depend oh the shape of the 3D object and the surface UV overlay.  Photograph are on a flat surface single plane. Your 3D object may have many surface and in different 3D planes.  If mat be very difficult to wrap your image into the surface UV.  Here I used many Image to wrap around the Truncated Icosahedron surface. You would need to use a real 3D application if to want to be able to work on 3D object surfaces well. Photoshop 3D is a nice addon but is limited. Take a look at Adobe dimension it may have features better suited for putting image onto 3D objects and its UI will be better suited for 3D than Photoshop UI..
