Hey guys, I'm having a bit of a problem getting an ortho photo of some ground to go 1:1 over a terrain I have. I cannot get the image to lie perfectly, even over a plane. I've attached an image. The plane is similar in ratio to the image size. Can anyone help me out? Am I missing a mapping mode or is this just difficult to do in Vue?

I'm not sure I understand: you want to map the terrain with the texture map we see in the material editor, right? Or you want to map a plane? Are the terrain/plane and image map same size, or have same ratio? I think if you used the object parametric coordinates system, it should fit, since this mode always returns 1.00 You might have to play with mapping modes, maybe faces.

Object parametrical works fine. The object's ratio and orientation must correspond to what covers the the map. In this render, the flat base corresponds to the map rectangle. Only a part of it was raised to terrain heigth (in an external program, not Vue, for this one).

How odd it works today! Much thanks!
