Sketchup has Face Me components and I believe some game engines can do the same..
also a way to scatter a load of objects would be good
Its very useful for grass and tree billboards
Can you describe a bit more detailed how your grass / trees are supposed to look like? That is, how many billboards do you have, how and where are they supposed to be used, etc.? Also a few sample textures/materials would be helpful.
Sketchup the 2D model in the default template is also a face me component
Its also useful if you wanted a surveillance camera follow the character
I just looked at GameGuru and that uses a more basic approach they use 2 planes at 90 degrees to each other

I just quickly did that, the material isn't right
Scattering stuff at a basic level its the ability to scatter objects on a named surface and maybe randomize rotation and scale and distances between each other
I just thought it would help if you plan to do terrains, I think Unity and GameGuru just use simple planes which can be adjusted depending on the quality setting and only visible in game
Same technique, but with models not in Cafu, made by others:

If you can do it like that, it is surely the simplest approach that gives the quickest results (because no coding is required) any may even look better than plain billboard sprites.
(An entirely different technique, from a project that I did at university and of which I wished I had finally time to implement it in Cafu: https://www.cafu.de/gallery/ --> select "outdoor" --> the orange morning sky)
Did you do the clouds?
