Interesting, if i change the background to white and change the texture to for examplea striped texture and only draw the colorbuffer on the screen quad.
I can see a white line instead...
I dont understand..
The mesh halfwidth is 12f, 0.5f, 12.0f, so it super easy to hardcode in the positions to be exact.
Forget what i just said...
I exported a new mesh, the previous mesh had problems with its uv.
The problem still remains with the point light.
I can see a black line, it still black no matter what the background color is.
