Sprites work fine in Quake1, like the light bowl.
It's perfectly round, so the turning of it won't matter.
With trees I tried once, but the turning of its flat side was rather anoying. It could work with round bushes or cactus though.
I remember having a hard time to get two sprites diagonally at the same point, or in clude it.
For now I'm happy with statics like
tree, because it hasn't that detailled surface, while quake's objects are rather cubick.
