Adrian,
Most likely your sphere doesn't have a material applied (i.e. it's
"invisible").
The best first step to debugging these issues is to look at the log
output. If you aren't getting any materials then you won't see
anything. Our loader doesn't render geometry unless it has a color.
Many people don't understand it because viewed in a modeling program
like 3D Studio Max you'll see an object color applied so you can see
your model as you build it.
Look for lines in the log file like:
Material Name: Material #26
Mat Ambient Chunk ChunkID = a010 Length: 15
Color 24 Chunk ChunkID = 11 Length: 9Color Value (r,g,b) =
25,25,25
Mat Diffuse Chunk ChunkID = a020 Length: 15
Color 24 Chunk ChunkID = 11 Length: 9Color Value (r,g,b) =
127,127,127
and then down further:
Face Array Chunk ChunkID = 4120 Length: 1715
Number of Faces: 120
Mesh Mat Group Chunk ChunkID = 4130 Length: 261
Applying Mat Name: Material #32 <- if no material applied
it's invisible!
Number of triangles = 120
