Installing

Copy the VolumetricExplosions folder from the download into your KSP GameData folder and start the game. To remove it, delete that folder.

Made and tested on KSP 1.12.5 on a Mac, and tried on Windows 11 (see How it is drawn for what was and was not tried there).

On a Mac, one more step if you downloaded the mod with a browser. The mod has a small library of its own (PluginData/vfxgrid.dylib) that does its heaviest sums. macOS marks everything a browser downloads, and will not let a game load a marked library without stopping to ask. So the mod does not try: it leaves a marked library alone, says so once in the game's log, and does those sums the slow way. The picture is the same; the frame rate while there is smoke about is lower (see What it costs). To have the library used, take the mark off that one file yourself, in Terminal:

xattr -d com.apple.quarantine "<your KSP folder>/GameData/VolumetricExplosions/PluginData/vfxgrid.dylib"

That mark is how macOS knows a file came from the internet, so only do this for a copy of the mod you trust. A copy you build yourself (see Building) is never marked. The log says which way it went: [VolumetricExplosions] grids are made by vfxgrid.dylib, or ... by the mod's own code with the reason.
