    Projecting 2D particle emitter to surface of a sphere

    Hello,

    I have a particle emitter which emits something like these growing magic circles on the ground when a magician casts a spell. I want to map these 2-dimensional particle system to the surface of a sphere. How do I do this properly?

    I found the following way, which seems to be very inefficient:
    - Create an actor with a screen capture component and a particle system component
    - Create a render target for the screen capture component
    - Make an instance of the actor
    - Create a material of the render target with material domain "deferred decal" and
    - use it as a decal. The 2d-decal automatically maps itself to the surface of the sphere, if you drag it over the sphere.

    Is there a better way?

    Thank you,

    Thilo
