Been doing some experiments today using OSM Road vector data together with freeware QGIS to generate street/lamp based “light splash textures” , comparing with current Sepia Mask illuminating huge areas of the daytime satellite photo. Lots of fine-tuning would be needed, but shows some promise after just a few hours of fiddling.
Here are some generated 4k textures of varying zoom over the United Arab Emirates, showing “mass production” potential. Please check original size, forum resizes images if you’re running lower resolutions lower than 4k. Comparing to this:
Given the results of my initial hit’n’miss attempts today, I believe it’s a method worth investigating more closely instead of settling for current low-res all-illuminating “Sepia Mask”…
