I’ve tried turning auto exposure off, overriding the light map resolution, using 2 sided lighting for each cube that makes up each maze wall but to no avail.
Looks like u it set to Preview mode. Change it to production. If its on production… you probably dont have a skylight. Just add one. It gives you Global GI.
Try importing from a 3d application. Honestly, never worked eith the inside package geometry so i would know how it would look. But just give it a shot.
It shouldn’t be an import problem as I’m using the standard starter content cube mesh and I can’t put a roof on it as I’m trying to get it to look like an outdoor maze with a sky?
Upon completion of lightbuilding the editor will inform you whether or not lightmap uvs are overlapping. You can also check in the mesh editor. Open your mesh, click the Display UV button and change the UV channel to the highest one (typically your lightmap). Check it to see if there are overlapping islands. If it’s a cube, it should have 6 individual islands shown within the confines of the UV space. Also make sure that the mesh’s settings for lightmap UV reflect the actual channel number.
