Theirry, The black triangles you are seeing might be faces with their normals flipped. Try rendering 2 sided and see if the triangles render. <<Are there an IPAS to make all booleans possible >> I'm not aware of any IPAS routines that enhance Boolean functions. If you need more Boolean editing that 3D Studio provides, your best bet is to move to a modeling package (like AutoCAD with AME or R13 and ACIS) which has a much stronger set of Boolean functions. Many people model in ACAD and then bring over the models to 3DS. -Brian
