Please make a Unity Editor Tool version of this. I think it'd sell very well on the Asset store since IIRC there isn't another Low-Poly tree generator on Unity Asset Store. Vegetation Studio and other shader makers(for animating vegetation. They have integration with Synty's Nature pack for example) will create integrations for this asset if you put it on the Store. Also the option to create low-poly trees inside Unity would be awesome.
Also, runtime generation of trees with some variation or randomness or uniqueness in Unity is an interesting idea to consider.
I'd like to know your opinion on this. Are you considering making a Unity Asset Store port? Or do you think it's not worth it? Or something else.
