The shades of the static meshes is not consistent with the source of light. If i move the source of light, it does not have any consequence on the shades. Then to “update” the process i launch “build lighting” and the window says “build lighting failed”.
when i add an other source of light there is immediately on the upper left corner a rd message say gin that the lighting needs to be rebuilt. it disappears when i set it to movable. so this part of the issue seems ok now. what about the other ?
