Hi, I just found your site through CG trader. I currently use Speed Tree for my plant/tree modeling but I do not use 3DS Max. I really like how your program looks, but as I understand it is only as a plugin for 3DS Max and the products and cannot be rendered in a real time engine like Unity or Unreal.
Many independent game developers(as well as archviz people) are using real time game engines and may or may not use 3DS Max. Many now use Blender or other 3d programs, then render their meshes in the game engine. I understand that making a plugin for all the other 3D programs out there or for an open source program like Blender may be difficult, but if you made a stand alone version it wold compete well with Speed Tree. I feel Speed Tree could really use some competition in this area as it is the only product I know of that can make quality vegetation relatively quickly for real time game development if you do not own expensive Autodesk software. I would pay for this program at its current price if I could use it instead of SpeedTree for my needs.
