Tried to find trees on the asset store but they all had problems with the materials and/or LOD which I didnt want (and dont know much about) in my game. So in the end I decided to make my own low-poly landscape and trees. Fun fact, I took the opportunity to learn about shaders in unity and decided to color my whole landscape with a shader. None of this was colored by hand. Its not perfect especially when it looks at the height of the object to either place snow high up on montains or sand low on ground but im proud of it and I learnt quite a bit from this adventure.
PS : Are there forums I can ask about shaders and have help with on GameDev? I would like to further improve this shader and I assumed asking about it here wasn’t the proper place.
