This is a tool for automating the process of making and using alpha mapped trees, which allows you to render massive forests of hundreds of thousands of particles in a fraction of the time and memory cost of using full 3D tree models.
This allows a lot of extra control in the materials and for winter/dead trees.
Overall, using the original method, it could take around 15-20 minutes to produce the maps for one tree, which this addon lowers to almost zero. It is only limited by render time, which usually takes around 30s to 3mins depending on settings.
How to use:

Ah, I think I may not have explained fully what was meant by that plant tree operator.
At the moment this addon can only generate the maps needed, and then they need to be added to your scene manually with the material in the provide blend file.
The Plant Tree operator is simply for fast import of botaniq trees for use with the main part of the addon (I will rename it to be more clear)
I will be adding an importer for these maps very soon though, so check back soon and it should be a lot easier to add these trees to your scene
hope that helps
I haven’t tried it yet, but as long as the materials are set up as described in the first post, the actual tree object shouldn’t matter, and it should just work (please tell me the results though, in case I need to change something)
Ah, that error shows if there isn’t a camera in the scene for it to render with. Did you use the “Set Up Scene” operator before adding in the tree?
I would advise starting a new file and using that operator first, before adding in your tree.
In the next update, all of that will be done automatically, so you shouldn’t get the error and it will hopefully remove a layer of complication.
hope that fixes it!
Using the “Set Up Scene” operator is now no longer necessary when starting a new file
Changed code so Addon should work on all platforms
Added proper error messages to common problems
Fixed a few extra bugs
Thanks, @MarioPeper for pointing out the holes in the addon (Though I’m sure there are more), If the problem still persists, would you mind sharing the blend file so I could have a look? I think I’ve solved the problem, but I didn’t manage to replicate the error.
Ooooh, so close! I forgot to update one of the files, but that download should work now
also, I tried saving in the .blend folder, but that requires that the file be saved first which can be a bit of a pain, and also, having it all in one folder lets you build a library which, will hopefully be accessed by the addon in the future
