I'm working on this scene where I camera mapped textures to a low poly model, behaves fine when in previews, but when I render it it simply distorts it.
As seen here and project files are here.

Seems that the stick texture tag is incompatible with camera mapping. Why do you need the stick texture tags?

I wanted to distorted the scene, so that's why.

it's the construction of the tunnel. Select the floor polygon and right-click and choose Remove N-gons you will see the kink in the rendered image occurs where the now visible triangle crosses the floor. The floor is one polygon and it needs to be redone and it should end up as quad polys. Delete the floor and put it back in with the Polygon Pen. The door on the left will be a problem too after fixing the floor as it is triangulated.

Ok, apparently I didn't know what you meant by quad polys? I tried to remove the triangles and use the polygon pen to draw quadrilaterals. I simply got distorted around the NEW vertices... and then I removed the floor again, and this time added a separate plane, but... its still distorted.. When I did remove N-gons it once again shown vertices that followed the distortion... Help?

you have to make sure you are getting the surface normals to all point the same direction as well. Here is a quick fix (it's not perfect but it's better) hopefully it will show you sort of the way to go.
