I don't know much about 3D modelling (only recently got hold of 3ds max 8, and never used it before). To better illustrate the problem, I have added some screenshots. The overall difference in the colour of the wall is acceptable, but the corner section as highlighted is pretty bad. I have been thinking of simply changing that area by crashing a vehicle in there, and dropping some boxes around (remove the bad objects all together).
From what I have gathered from this forum it might be missing uvmaps? samplesmaker just crashes on these objects (have no object lightmap). Maybe someone can guide me a bit on this one? How do I fix the objects? someone already done it? or just do a workaround? (or did I stuff something up..)
