But on the back the mesh is transparent:

  • $\begingroup$ I don't know where this is in 2.49b, but try disabling "backface culling" $\endgroup$

  • $\begingroup$ @GAMELASTER then you might have to make it have some thickness. (I don't know if 2.49b has the solidify modifier, but you might be able to just extrude it) $\endgroup$

Try adding some thickness to your mesh.

It seems to be currently a 2 dimensional plane, which will only have one side drawn unless double sided faces is enabled.


It seems that double sided faces was removed in 2.6x.
Backface culling can also cause this. The Backface culling setting is located in 3D view > Properties panel > Display:

  • $\begingroup$ In 2.5x Double Sided was moved to Mesh Properties under Normals. The backface culling option was added in 2.64 but the back of the poly should be visible in solid mode, it's only textured mode that hides the backface. $\endgroup$

  • $\begingroup$ @sambler thanks :) fixed. (though backface culling does seem to effect the mesh in solid view?) According to this, double sided normals is not the same as double sided faces $\endgroup$

  • $\begingroup$ backface culling will make the back transparent in solid and textured mode(2.64+). 2.49 that GAMELASTER is using doesn't offer that so textured mode or texture solid should be the only time it is transparent. $\endgroup$
