Im having a frustrating problem with one especific model i imported from archicad to sketchup. In Sketchup everything looks normal, the axis are as the should be, but when I make a render the horizon plane is not completely horizontal, its inclined, and it kind of chops my model in half, no matter where I move it, its still the same, i even copied the model to a new document and its still there. I dont know what is causing this, at first i thought it was my HDRI background but even with the default render settings the problem persists. Please help me. Here are some pictures.
I added a Vray Infinite Plane hoping the other one will disappear but it didn't. In the picture you can see the Vray Plane (The lower horizontal one ) and the inclined one which i cant get rid of.
