Any solutions to fix this artifact on the object lightmap , i tried to use the custom lightmap resolution to value 200 but nothing could help
It looks like the object’s geometry isn’t smoothed. What 3D software does the scene come from? Have you set smoothing for the chair object?
thanks for your reply , it exported from Sketchup . Does the smoothing modify look the same with turbosmooth in 3dsmax ? . I’m not using Sketchup rarely . Sorry for asking !
In SketchUp use the Soften Edges tool, as described in: Softening, Smoothing, and Hiding Geometry | SketchUp Help
