City Christmas trees in two sizes 14 and 22 meters in height. Fir-trees are assembled using the Multiscatter plug-in. Those who are lucky have nothing to do except to place it in the scene.
For those who use other scatters there is another file option. In it, the balls are stuck in the object, and the branches will have to be planted with your scatter. Also in the archive you will find a screen of settings that were

applied by me in Multiscatter, but there is nothing tricky there, I think you will guess. Unfortunately, I could not get rid of the needles, because firstly, a very heavy object would turn out, and secondly, the model would not fit into the base.

I hope someone will come in handy.
