I’m testing how the solid mesh (monkey) affect the solid texture (photos of leaves and man) with an alpha channel using the Blender’s Cycles (ver 2.64a) renderer. Using the sun as a light source with 0.003 size. Other renderers like YafaRay have a strange shadow when it comes to alpha channel.

Sample scene set-up:

Here’s the material setting for the alpha channel (after the uv mapping)–same setting for the man’s texture.

Sample render in Cycles:

Sun's position above, using .003 size for the shadow.

Changed the sun’s position:

over-exposed.
Well, it’s over-exposed.

Lowered the exposure in the renderer:

Lowered the exposure to 0.20 in the renderer.

With the right lighting and shadows, adding people in the 3D environment is a nice addition.

More testing to come…
