This has worked for me years ago using this program, but right now bright blocks do not glow, even though I've checked and the setting to do so is enabled and high quality rendering is on. https://imgur.com/a/grMz7LB https://imgur.com/a/Csmk669

Is there any way to import WorldEdit schematics from 1.13 and newer versions of Minecraft? The new .schem files WorldEdit saves cannot be recognized by mine imator, and simply renaming the extension to .schematic does nothing either.
