Particle emitter not working in game

[biridius]

I tried to make a projectile's Death animation have a larger explosion.
Edited it in war3 Model Editor, everything seems to display fine in the W3ME.
But after importing it in my map, the yellow flash in the middle of the blast (particle emitter BlastFlare) does not work. This makes the explosion look very dull.

What could be the cause? I tried playing around with parameters like Blend/Additive or model's bound radius but nothing seems to work.

Edit: another detail, when viewed in the World Editor, the flash in question sometimes is visible, and sometimes isn't, seemingly at random.

Could be the extent of the sequence itself. Try recalculating extents.

When I use the editor's "Calculate Extents", it sets extents to a very small number that is much smaller than the flare that is not displayed. It seems to ignore particle emitters and only care about the model's geometry. I saw no difference before or after using "calculate extents", or after manually rewriting all extents to a large number.

Another particle emitter (creating ring-shaped shockwaves on the XY plane) with pretty much the same size and other settings in the same model works just fine and is displayed in game.

When I open the model with Hive's "sanity test", the death animation sometimes shows the flare, and sometimes it doesn't, same as in the World Editor, but in the game it is never displayed while the rest of the model works.

I opened the model Magos, and whenever I make changes to the BlastFlare emitter, it seems to totally bug out.
Try deleting it, save the model and close it, then open it again and manually add the emitter again.

Seems to work now, thanks for the help!

No problem!
