Any word on if or when Keyshot will get a Camera Projection mapping option?
I second this request.
This is very useful for defining ground material. You can project the environment on to geometry, then project that onto the geometry so that the objects reflect the base surfaces correctly. If you've got a box sitting close to the objects it looks a little odd that it reflects as if it's 200 units away as part of a sphere.
Yeah, the flatten option helps, but only for flat ground. It doesn't help you if you've got a rock nearby, or a wall that needs to appear like it's really close to the object.
Camera projection is available in KeyShot 6.
