i wanted to make some modular tree tiles. these use some fun tricks, so i thought i'd share in case anyone might find it interesting or useful.

this is a set of 16x16 modules. the bg trees work as continuous fill (left) , but a single layer will appear as nearer trees with distant trees behind them (center top).

mid-sized (2 tile high) trees use a slope variant with a stem at the bottom, which does dual function as leaves when it's used as part of the canopy in foreground trees.

the large stem is 1 module. the right half is rotated through half a circle with a different palette.

tiles where the trees pass over rock are a recolored and rotated rock sprite.
