At times, you will need particles to be emitted from bones of a Skeletal Mesh, such as a character. In this effect, we demonstrate this with a character that seems to be having a little bit of a problem with a certain amount of flames climbing up his arm.
This effect is achieved by way of the Bone/Socket Location module, which allows you to spawn particles from moving characters/Skeletal Meshes. You select the bones or socket names from where you want to spawn, and add a parameter name.
Then, in the Emitter Actor properties, you add the instance parameter with the name you specified before in the location module, select PSPT_Actor from the list, and select the Actor (Skeletal Mesh in this case) you want to emit particles from, and you will immediately see particles spawning at the bones/sockets you specified in the location module. Done!
