Console commands that allow saving, loading and overriding lightmap resolutions in bulk for faster light build iterations

  • Supported Target Platforms
  • Supported Engine Versions


The plugin contains three console commands that can be useful in situations when you are lighting a part of your level and need to rebuild lighting multiple times, but are only interested in that part of the level you are working on.

SaveLMRes: saves data for each static mesh in the level to file. The data saved is if the lightmap resolution is overriden and what the overriding resolution is.

SetLMResTo1: overrides lightmap resolution for each static mesh with 1.

LoadLMRes: reads and applies data saved by SaveLMRes.

The location of the file is \Epic Games\UE_4.15\Engine\Binaries\Win64\LMRes.csv
