Why does GetTextureCoordinate return uv>1

Hi guys

I am trying to use GetTextureCoordinate api to get uvCoords. However, it returns uv>1, which is quite werid when I export the "tree plan/billboard". I find that uv>1 means repeat the texture for uv times but the "tree plan/billborad" should not repeat itself.

Could anyone help me please?

Maybe "tree plan/billboard" should be a 2D object itself, whose width is 0. GetTextureCoordinate doesn't give uv directly. You should divide the results by X (x of the texture) and Y (y of the texture) respectively.

That's good to know! Thank you for update!
