And here is what we get after build finishes.
I’m huge confused by this weird shadow.
I have no idea about what is causing this. Resolution? Shouldn’t it looks like blur if the resolution is too low, instead of writhing in a coquettish way? Multi-light source? No I only have 1 directional light and 1 sky light in my map.
Anybody can figure what is happening in my lighting building? Thx.
This looks like low lightmap resolution, also are you sure that your lights are static/stationary?
Post a screenshot of the alt+0 visual mode, if it doesnt work, go to the Lit button (inside the viewport, to the right side of Perspective) > Optimization viewmodes > Lightmap Density and take a screenshot.
After hit Alt+0, I immediately realize it is indeed a resolution problem when I saw all the screen turns into deep dark blue.
Amazing. So I tweaked the resolution until it seems like a little green.
It works as normal now.
