MaxED had added it to GZDB and when asked why it does not work, he said that GZDoom had not yet implemented it.
This seems to be born out in that GZD-x64 g2.4pre-219 still does not respond to the editor settings.
When checking rheit/acc/zspecial.acs I find
Code: Select all
// GZDoom OpenGL
-400:SetSectorGlow(6)
