Fire propagation setup?

Development Getting Started & Setup

Hi guys,

New user here guys and sorry if this is a dumb question but…

Im looking to make spreadable fire across a landscape and in the future set fire to objects it spreads into.

My question is what is the best way to setup my plane to uniformly spread my fire objects upon? I have currently just made a fire blueprint that spawns itself again in one direction after 3 seconds. I’m not too worried out the speed and direction of the fire ATM I just want to make sure I am setting up the ground it is travelling along first.

I’m just confused to how to do so, my idea was to have the ground split into cells but I don’t get how I do so? Do I make the ground out of multiple small planes? This seems like it would be a terrible idea… I just wanted to some how make a grid of cells upon the plane…

Sorry if I’m waffling on and thanks in advance for any help!

Hey @Liam789 how are you?

I found this tutorial to creat a Fire Propagation System and I highly recomend you to watch it as it tackles the topic you are asking for! It teaches hoy to properly setup the ground and objects that can be set on fire, so I believe it will be helpful for you. Keep in mind that the tutorial has a second part here.

The tutorial was made for UE 4.26 but, as you can see here, it works for UE5 as well.

Hope this helps you with your system!
