I've an .stl file of a cube of a porous material. The material is basically many overlapping spheres. Since I imported it as an .stl file, it is one object to blender.
I want to have an animation, that clips through the material. Can anyone help?
I tried using outside lamps and camera clip, but then the inside is not illuminated. Also, once a sphere is "cut open" by the clipping, you can see through it. I don't want that. Solidify doesn't do the job, because the spheres have different radi.
