Transparent Seam?

[Nragemachine]

Okay so I’ve been trying to make a human model and what I did was after sculpting
I cut it in half, duplicated, mirrored, and then joined the two halves by creating
new faces between them and then joining them so that they are one mesh.
But as you can see below the render itself looks presentable, but the view, particularly
when showing texture, shows this transparent seam. I plan to use this model for a game
using the Quake engine and want to know if this will appear in the game or if this is a problem.

So please help me find a solution, unless this isn’t a big problem anyways I just want to know
what I should do, thanks!

You need to recalculate your face normals so they all face outwards. Select all your verices (A) and use Ctrl+N

I’d also merge these vertices together so you get the vertices running down the centre of your mesh. Seelct them all and use S (scale), X (along the x axis), 0 (zero). Then remove any double vertices with W / remove doubles

I understand now, thanks!
