Hi,
I would like to animate the box which adds the point to the “hot” group for ignition.
If I animate the box, it adds the points to the group, but the fire just ignite in the first frame.

I can't figure out what I need to change to get the animated box to ignite the fire.

I attached the scene.

Thanks for any help
Tom

dive inside of your simulate_spread node
and insert Point Wrangle:

Thanks Tomas
