sup,
there is an AddonNode under the Special Effect tab in the CK.
its called mpswaterboilbubbles, when i place it into the render window, its massive, its roughly 100x bigger than my interior.
i can't move it, and I had to delete it. it didn't work in game, i have an interior with a few different water models in my bathhouse.
Also, in general, how would you normallly use a special effect in the ck?
