i have just recieved a flame how do i upload it and make it work. do i need a flame texture?

alright, so if you have a flame particle texture, then you can get a picture to make the flame particles change to the textures, but if u dont have one, the flame still works
to "make it work" just press the "activate" button next to the flame in your inventory, itll work after that

Also,if u have a flame particle texture, u will be able to even change ur flames colour.
