Hi, All

I am a newbie to blender and unity3d and encounter a issue when I import a blender modeling to unity3d. To simplify the issue, I create a cube in blender and unwrap it in UV mapping. Then I import the cube into unity3d. Here is the image.

The left one is a cube with blender modeling. The middle one is also a cube with blender modeling, and I add a grass material in unity3d. The right one is a cube I created in unity3d, and I add a grass material in unity3d.

Here is a issue. The middle one has some shadow in its faces, and the right one creating by unity3d has no shadow.

Why the cubes are different? If I don’t want the shadow, how can I do?

Thanks!

I think I got a solution for you,
go to your cube’s import setting and under Normals Tangents, set Normals to calculate and the smoothing angle to 0.
Don’t forget to apply changes.
