Simple realistic candle flame (micro-tutorial) Work In Progress

I stumbled on this by a lucky accident. I find it very useful from time to time. + Flame is a very thin rectangular cube. OK to texture front and back. + Flame texture is a single PNG image of a flame (emission / transparent). + Flame mesh is animated with a single bone at its base (Armature modifier). "Preserve volume" must be on. + A Point lamp is also parented to the same bone, near the tail. It casts nice shadows, especially in Eevee. + Add some random noise to the bone: rotation X, scale Y, rotation Z. (With a modifier if you are lazy, or keyframe manually if you are ambitious.) + Play the animation and tweak all the parameters until it looks nice and realistic. It's handy to define the noise to make the animation loop seamlessly.
