Textures are dark when imported from Cinema4D

i have a player for my game and have baked it withing Cinema4D but when importing it to Unity3D the textures are dark. I have tryed turning the Ambient Occlusion up but only maked it slightly better

Here is a picture of what it should be and is (the ambient occlusion in uniyt3d is full and a directional light is realy bright)
