Solid rendering has no directional lighting as you can verify
changing the light source direction using Tools / Viewing Controls /
The default solid rendering mode uses OpenGL 2D textures stacked up
along the data axis (x,y, or z) most in line with your view. You
probably are seeing artifacts related to that. You can try switching
off "Solids using 2D textures" in the volume dialog "Solid rendering
options" panel. With a high-end graphics card that will use 3-D
textures that don't have as many artifacts. If your graphics card does
not support 3D textures you will just see an outline box with no data.
