Hello everyone,
I’m just starting with blender and I need a little help.
I’m modeling a character for animation, output to low res bitmap. All I need is the
character with a white background and their shadow slightly behind and left. Sort of a
top down view from upper right side.
I have the model built. I put in a plane perpendicular to the character and set material
for the plane and sky to white. I set up a lamp (for shadows only), on the same layer as
the model. The plane with lamps to illuminate it but not the character on a second
layer.
Now, the render looks good except for some bleeding of the colors of the model and it’s
shadow. I have OSA off. What I need is where the shadow is, just plain black, no
lighter shades of black or grey on the border. Same thing with the model, the
outermost pixels (in bitmap form) where the lights hit it are lightened.
I’m using a white background because where I’ll be using the images, white is
transparent. So anything not exactly white shows up. Is there a way to light this scene
or some setting I’m missing that would give the effect I’m looking for. I know it’s kind
of complicated, I’ll try to explain a little more if you cannot understand what I’m trying to
achieve. I know Blender was not meant to output low res images but I know it can be
done. 
Thanks in advance
) You are going to get some edge anti-aliasing, which means some gradation pixels. Anyway, to get black-no-gray shadows, you will probably have to post-process the shadows in some manner. My guess is that you want to process the shadow and not the model, which means you will need to do some compositing.
