Light map artifacts on smooth Object

I have alto generating a lightmap for the object and I am having artifacts. I do not know the best sort of lightmaps to use for this sort of object or a way of fixing the artifacts, do you have any suggestions?


  1. The lightmap resolution is very low, some tiny UV islands don’t get even a single pixel. If you set the lightmap resolution to 64 you will get a much more better result!
  2. Try to create lightmap by hands, because your source UV(0) have so many tiny UV island.
