I suspect this is a GZdoom problem rather than one with LIGHTS.WAD because I can't see anything in LIGHTS.WAD to allocate a light to these sprites but when you use a porkalator on one of those flying FireDemon things in Hexen, you get a glowing pig running around. ie, although the thing is now a pig, the dynamic light is still attached to it.
Actually, I quite like the effect because it lets you know which pig was one of those FireDemon things to start with. However, I suspect it is a bug.
