weird shadows on custom object

[ChaosLasse]

Hey everybody,

so I made this buliding in blender and imported it into the game.
Now i get weird shadows all over the place.

I already tried:
-changing the sun angle
-join all objects in blender into one object
-cleaning up faces that are not visible (in blender)

I allways reexported the object as an .obj befor exporting as .jm
(since some changes would'nt save when scipping the extra export)

I would like to release some of the objects i did, but i want them to look how the are intended to.

These are the shadows that i am getting...
Sun from behind:


Sun in front: (Back side seems good though)


Do you guys have any idea on why thats happening?

Try using an edge split modifier, should fix the weird shading in the first pic.

First, Remove any doubles. Looks like there might be some. Secondly, bake a norm (best way) or edge split your corners (lazy way)

The weird shading you see is the game applying the standard smooth shading to the model. In blender, click your model in object mode and set the shading to Smooth to get an idea how it will look in game if you don’t bake a norm.

Thanks guys,
