Awesome!
Thanks for the info 
Oh totally forgot to ask two things so you get a free bump.
Will this work in multiplayer and Will this work with Instanced Static Meshes?
If by “work with” you mean will they catch fire, yeah, currently as long as they have collision.
I haven’t done much with multiplayer/replication stuff yet but I imagine it’s pretty easily replicable. I’m not super experiences with that so might not be supported at first
Would it be possible to make fire only and spread across flammable surfaces? (Certain materials).
So for example it will only spread on wood, cloth and vegetation but not on rocks, water or sand.
Any updates on this? Looking forward to it.
I want this. I have no idea what I would use it for, but I want it.
