Sorry for the late response, but we have good news. One of them is that the project is not dead 
We had a bunch of alpha testers that we would like to thank for their input, and now we have decided that a public beta would be in order!
Go to our website to download a beta version of our plugin with the frog model included 
You cannot generate other models with it but we would appreciate it if you would try it out!
Please do mind the system requirements:
- Newest Unreal Engine (4.8.3) launcher version (not the Github version)
- NVIDIA GTX400 series or newer (compute capability 2.0 and higher)
