With axiom 3 it looked like this

Little question: playing with an older axiom 3 setup where I turned the fluid into fuel and added temperature at a specific frame so everything ignites. Doing it on aiom 4 gives me some very local ignition but the fire isn't eating through the fuel anymore. Its basically everywhere the fluid from the bottle is.
Anything new in axiom 4?

Hi,

I would like to know how to get the connect adjacent pieces to only intra-connect pieces and don't generate connections between areas like windows, frames etc. I want to generate them myself. How can I do that?

They have different names, should be doable somehow.
