make an image in paint. color it grey (128,128,128). then draw a white circle in the top left. it'll like this
where . is white and # is grey.
then save it, and in B3D, loat it like this
celshade=loadtexture("celshade.bmp".1+64)
and texture your objects like this
entitytexture <entity>,celshade,1
and make sure you
entityfx entity,1
