Here is a silver birch, minding it’s own business. It looks close to dropping its leaves. I made it using Blender and its ‘Sapling’ tree generator, which produces a bunch of curves for the trunk and branches (based on your inputs) and some simple planes for the leaves. I wanted to give the trunk a texture map, so I converted the trunk curves to a mesh, UV unwrapped the mesh and created the birch bark texture in Krita (as it has a nice pencil tool).
Here’s a picture of the mesh if you like that kind of thing:
Why am I making trees in Blender? I just have an idea of a little game I’d like to try out and I like the thought of using Blender and Unity3D. I’ll post up progress from time to time.
