Hey, so I just had a couple situations where I potentially needed to add trees to a couple scenes I was going to be working on, so I needed to find the best way to approach that. It seems it’s definitely project dependent; as there are tons of different directions you could go with it. You could created them from scratch in your preferred 3D application. You could use something like paint effects in Maya as a starting point to create your trees. You could develop them from scratch more easily in a program made specifically to create trees. Or you can buy pre-made trees in various bundles online. It all comes down to the scene you’re working on and what would be best for you in your current position.
