I have created a low-poly model of a campfire in Blender which looks like this:

In Unreal I have messed with the fire material and it has ended up looking like this:

Is there any way I can get the material to look like it does in Blender. Any help appreciated!

Something along these lines? you can lerp to the darker colour based on normals (or perhaps paint vertex colour Red on the tips and use that as a mask)
