Lumion3D is a great rendering/visualisation tool I hope to be using much more in the future.   It might not give you full control over everything but if you want quick and easy renderings of your models it’s brilliant.   A word of caution though, you might want to upgrade your graphics card… (or like me your entire PC).   You can download a free (limited feature) trial now from here.
