I noticed some artifacts on smoothed thingmeshes.
I guess its in the lightmaps, it seems (for me as non-programmer) that there is no smoothing while lightmap generation or the interpolation between lightmaps is not good.
The right object is a genmesh which is smooth ok, because genmeshes seem not to use lightmaps at all (or is there a way?).
I used simple textures to show the problem clearly, but even on objects with normal textures you often see artifacts. Maybe I can do something against it (tried the -lightqual and -lightmapsetting with no luck) or is is a matter of the renderer (new renderer was used)?
