Making realistic fire

Hey, can someone help me make realistic fire for a fireplace(without using photoshop)? i have watched sooo many tutorials but i still can`t figure it out.

By ‘without using photoshop’ do you mean at post-processing, or even for the preparation of textures?

For the preparation of textures. I watched this tutorial and it is all clear on what steps i have to follow, and i also found ‘’ fire pack cut outs’’ that already have the background cleared out but it still don`t look realistic.
