I really need a better version of this hack
https://neverwintervault.org/project/nwn1/hakpak/original-hakpak/rays-light
ProjectQ offers some good rays but they are colored (and only in one shape)
Coud someone make some white rays? (No E.E)
You can make white rays easily enough with a text editor, just change the “color start” and “color end” parameters on the emitters to “1.0 1.0 1.0”.
If the mdl files are binary files, you’ll need to use NWNExplorer 1.83 to extract them as ascii format.
If the texture is colored, just make a greyscale version of it and you should be all set.
