I think the top section of the La Vieille lighthouse is pretty much ready. Those are some quick previews (sorry, no HD renderings):
As you can see, I have added quite a lot of 3D detail, and textures look much better though I probably need to tweak their hue/saturation/luminosity/contrast a bit (the red dominant comes from the picture I extracted the textures from).
Floor level and rocks still to do.
Other than that, I would like to bake an ambient occlusion map for the model. I have tried to mimic one by exploiting the shadows already present in the picture said above, but indeed the 3D feeling would greatly benefit from a proper map. I don't remember who told me that SHIII shaders support either AO or normal maps. If someone could explain to me which controllers need to be used and how to set them, I think that could be a nice addition
