ehh... Hi how do i change my flame plane?

Would you mind explaining what you mean by "flame pane", if you mean buy a flame particle texture then go here to get a flame texture. If you have this already and want to buy art for your flame then go here and search for one.

i mean how do i get my flame particle off... i cant get it pure black cuz when i get it off flame particles are still there to customize..

Did you try redownloading your customs? Try deleting your custom folder then download it again
