I've been lucky enough to get a hand to tryout an awesome software LUMION 3D.
very suitable if you try to make an animation out of your sketchup model. quite fast (depending on your rig of coz :D)
but still unmatched to the power of vray :)
very fast to produce, equipped with their own set of 3d library which is awesome!!. especially on the vegetation parts. the picture i attached below doesnt have any PS work in it, just fresh out of the software. did not require much time spent learning on it. Pretty good tool for someone who need their job done quickly. and the best part is....... IT ... CAN... PRODUCE .... AN... ANIMATION... quite fast comparing other regular 3d rendering software
