Fire Exchange between Geometries

[mzwarg]

I am attempting to roll an object across a surface that is on fire and will light the ground behind it on fire as it rolls over it. How might I make that exchange happen? Any tips on strategy or concepts to look into? Thanks

perhaps the best way is to use particle flow, make the rolling objetc to produce particles and create the needed graph that transfers them to the contact point and of course use the particles as fire source.
