I light everything until its pretty. Then I rebuild the lighting and 15 minutes later, when its finally done, everything looks completely different, way darker. So how am I supposed to create good lighting if the outcome after rebuilding it is completely different from the preview?
Constantly rebuilding is not a real option because it takes so long.
I’m a big fan of having a small test map with minimal geometry that allows for very quick light bakes to test out different approaches. Sometimes you just have to try stuff and see what happens, but doing so in a full production map can be slow. Building on preview quality and lowering lightmap resolutions is also helpful if you want to just speed up your bake times at the cost of visual fidelity. Once you’re happy with the value and color balance of your scene, you can crank your settings back up to get those crispy shadows back.
