Free 3D landscape creation software "Terragen 2" can also render stars and plants

This is all 3DCG. It is said that it is available free for non-commercial use as before. Of course this plant is also 3DCG. It is a good era that such a thing can be created with the same operation feeling as existing Terragen.

How easy it is to create can be understood by using the previous version of "Terragen".
