so, i make a tree in blender using tree sapling gen, then, i imported it to roblox and got something weird!
the terrain color is changing! on the area around the tree! i wonder whats causing this, and if i know it i can make some cool things like a swamp in center of a normal forest!
I don’t know what’s going on but it looks like a shadow? I can’t really tell because there are multiple dark parts.
Its your Studio Graphics Settings
Those are just the shadows. Roblox renderes them weirdly sometimes when it goes on mesh parts. 
But, ngl terrain color change in different Areas would be nice. 
Have a nice day!
