I put a model ingame from obj format. The textures look fine, and in MSHViewer it looks fine, but in-game it's darker than it should be. The only lighting I have is a bright directional light as well as the light settings from the stock Mos Eisley sky file. Here's a pic of the model in MSHViewer, showing what the textures look like and how the model ought to appear: And here's a screenshot in-game: The roof is clearly much darker, to the point of loosing detail. The bottom stone section has a similar problem. The walls are ok, but still darker.

How could I solve this strange problem?

Delete and reapply the texture materials, I saw something strange on them when I exported the models.

That did the trick, thanks.
