Tree It is a powerful free tool by Evolved Software that is capable of generating customizable trees for real-time work. It works with any standard DCC tool or game engine. Also, the tool supports a range of tree types, coming with tons of options for adjusting form, like a polygon reduction slider. Tree It exports the geometry and textures in OBJ format.

Initially, back in 2012, Tree It was a commercial tool for Dark Basic. Since then, the team has upgraded the tool, with the latest version revealed in July 2017. Now it exports in OBJ and .X formats, making it compatible with most standard game engines and DCC tools.

• Create high-quality 3D trees
• Edit joints as well as break joints
• Create any tree, not limited to just one tree type
• Adjustable LOD slider
• Render to image for leaf creation
• Exports to *.dbo *.obj *.x
