I have a problem of visualization after the calculation of the lightmaps. After i do the building, my lightmaps are not correct… there are many black spots on my surfaces. In several cases i have solved just closing and restart the project. In other cases this procedure is not sufficient. More, other problem when these shapes appears is that the texture are not defined. I would to know if this is only an effect of a not completed building, due to some Load Errors that appears into the Message Log. In the last building for example i had some Load Errors of some assets that were into the browser content but not into my level. Is it possible that this caused an interruption of the building ?
Hi. It seems to me your lightmap has either very low resolution (have you tried to increase that?) or your geometry has lightmap UV coordinates shrinked to a very small portion of the lightmap area. Erroneous loading of assets that are not used in your level should not cause this.
Hi, thanks for reply. The resolution of lightmaps seems correct, i have inspected it by the Lightmap density view and overriden it where opportune. About the geometry, i have modified all the meshes by using an unwrap modifier (and then flatten mapping operation) in 3DSmax before import into Unreal. Now i will try to force no precomputed lighting and then to retry the build.
Now the problems are increased. It is not possible now to make Build… I have the error “Kicking off Swarm”. I tried to remove all the mesh that are in my level and re-import them and it worked. Someone can say me why I had this problem… what is the cause that my map it has been corrupted suddenly?
