I have this particle size problem… Am I crazy or are these particle plumes different sizes? These objects are similar sizes, but the plume for the enemy is smaller and I do not know why. It’s the exact same particle being played. What can be happening here?
Only difference between the two is the player is a static GO in the collection while the enemy is spawned from a factory. Both have the particle effect attached to their GOs.
It looks like one of them is scaled. Are you applying a scale to the game object?
The GO has scaled sprites only inside of the GO. the GO itself is not scaled.
Can you please share a minimal project where this can be tested so that we can figure out what’s going on?
I will post after work with an update to this post. Thx.
Funny enough, the minimal project plays it properly. And I have it all set the same as my project.
But when run in my game, it looks like the above. If I create the smoke from a factory, then it plays properly.
Ok, and what if you start to strip down your project to only contain that factory and game object and remove everything else?
At this point it would be more of a task that takes up too much time. 
The factory works, so I do it that way. If I find some time, then I may revisit it. Thanks for the help.
