Import model from Cinema4D = black textures

Hi,
I try to import this .c4d file into unity (I put it in the assets folder of my unity project)
https://www.dropbox.com/s/9o9jbghc38ct37x/SW_Port.zip

but when I drop it into my scene in unity, all the materials are black

If I bake the texture if c4d they appear correctly in unity, but it takes more place , is it the only way?

thx for your attention
have a nice day

 

You have your "Main Color" in the Unity Inspector set to black. Change it to white.

To avoid this at import... in C4D, move your baked texture from the Luminance channel into the Color channel prior to exporting to Unity.

 

thx,
I finally did it ! and without any baking
In c4d : materials = Color / add
In Unity : materiales = Partilules /Alpha blended
