Hi,
I wrote a program that uses lib3ds to create a cube and write it to a 3ds
file. Each face of the cube is made up of two triangles. I could open the
file fine in some viewers but i got the error "improper file format" when
opening the file in 3ds Max. My code is below. If anyone has an idea of what
I might have done wrong, please help me out.
Thank you,
Adrian
