Vanishing Point Two Point Perspective 3D

Question

I'm trying to add 3D models of furniture into a photo of a vacant room. I am able to use the vanishing point filter and match the "current view" to it in 3D for certain photos. It works when the camera is pointed perpendicular to a wall (one point perspective.) But I can't find a way to line up the vanishing points so furniture looks correct on it. Here is an example of the photo I'm trying to use.

HiThe vanishing point plane does not have to be straight on to work.In vanishing point just select an area of the floor and layout a plane that matches the tilesWhen you take that into Photoshop you may need to adjust the camera FOV. Normally this is automatic but with the angled plane I found this step necessary. Just adjust the FOV value to match the "floor" plane with the background (don't move the camera). I needed to make FOV 13mm for your example.Finally - turn off the opacity of the temp floor material and change scene to solid rather than unlit texture.Place your objects,Light and render. Rough and ready below but hopefully you get the idea.Dave

There is no such thing as a two-point perspective in real life. Two-point is merely a drawing technique - a camera always has only a single focal point. In your case the killer is the extreme wide/ fisheye lens effect, so unless you start to unwarp your image, use better lenses or use a more sophisticated 3D tool that can deal with this stuff, this won't work.
