Terrain Color change on one area but not the other?

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. :sweat_smile:

But, ngl terrain color change in different Areas would be nice. :thinking:

Have a nice day!
