The Curse of the Square Particles has afflicted my mod once again. This time, the smoke effects on Barad-dur have turned into squares.
Spoiler Alert, click show to read:
The cause of this bug remains elusive. I recently fixed the trebuchet/catapult and ballista smoke trail effects (which had failed randomly again for probably the third time) by replacing whatever .tga they had in descr_arrow_trail_effects with Oil_particle_2.tga as per Gigantus' tutorial. Eventually, all my particles will be Oil_particle_2 at this rate. I can only guess that these projectile effects somehow broke the smoke effects on the Barad-dur battle map as I haven't touched any of the other effects files or the models_effects folder.
Does anyone know how to edit particle effects on battle maps? I checked IWTE but don't see anything obvious. I suppose I will need to throw Oil_particle_2 at the problem again but I don't know where the particle textures for battle maps are specified.
Beyond that, does anyone know definitively what causes the curse of the square particle effects? Why changing the .tga used for an effect in descr_arrow_trail_effects might cause effects on random battle maps to fail? I would like to know once and for all how to avoid this bug because this game of whack-a-mole with Oil_particle_2 is getting a bit old.
