you can also try these free one Render! Simlab Composer Lite! (very easy)
Advantage you can blend a lot of 3D formats of File!
Careful even 3dm format is present don't use it! (it's just special polys Rhino and not Moi's Nurbs!
All other 3D Nurbs formats are available! ;) (Sat, Step, Iges prefere the Step format) and of course any others! OBJ, FBX etc...

Create 2D Ground / Import a 3D File (any formats except 3dm!!! )
Have fun!

PS Maxi 1900 * 800 but with something like this free one Upscayle you can have have *4 or *8 !
