Hello, I'm sorry for that the text comes later than my bid, but I was on mobile and my connection got interrupted. I find that your project is of great interest to me, but first let me introduce my self. My name is Todor and I do things that thrive on the border of art and technology, let say a creative coder or cross media artist... But I think I have all the skills for your project - I know the ins and outs of Unity 3d, I produce a lot of 3D content - from modelling to final render. At the moment I am deep in to procedural content generation from both artist and TD perspectives, so there is no better exercise than growing vegetation. :)
Just to make clear : what you want at the end from me is animated and scripted prefabs?
Anyway, It will be a great pleasure to help with your project.
All Best!
Todor
