[DOOM] FIREBLU in Plutonia
I've just been re-reminded of this: It's technically not a bug, but is a bug.
There is a long standing oversight in Dday's ded's with Plutonia's FIREBLU animation.
Dday includes a material definition that makes FIREBLU1-2 full bright (for reference Vanilla Doom didn't support full bright textures/flats), for the Doom1-2 and TNT animation. However, Plutonia also uses this material definition, when it actually needs it's own due to the Plutonia animation having a different number of frames to the Doom1-2 and TNT animation.
This mistakenly causes the Plutonia animation (start of Map02) to flicker In brightness, when it calls the frames named FIREBLU1-2.
