Will fire behave differently if i turn off ships gravity since fire in a zero-g behaves very differently from fire within a gravity well.

For initial release we won’t have fire in zero-g environments.

Propagation tech is gravity aware. We have an approximation which will influence the strength of convection based on gravity. This does account for zero-g.However, currently we don’t have visuals to show the difference between zero-g. As you posted, fire looks very different in zero-g.
