Hey there, I recently successfully learned how to split a triangle across a plane using these equations: Coord A + B opposite sides of plane V = B - A Distance = Ax+By+Cz+D where ABCD are the plane values and xyz the coords of A. Take DotProduct of the plane and vector V. ValueNum = (-Distance) / DotProduct; Intersection Point = A + (V * ValueNum) OK,..yes, glad I understand this now BUT...... I''m having difficulty in gettin'' the texture coords of each of the new triangles made, abit of a mental block I think. If anyone can help I would be very grateful. Thanks again
