A long and scripted FX with as subject to make a cube appearance with cool effects (and in Unreal Engine 4)
The breakdown of this effect is as follows:
At the beginning we have a vortex, then a glowing sphere comes out of the ground. It exploses and a spinning cube (which levitates thanks to multiple sphere around it) appear on the air. Then suddently, it’s falling down and instantly breaks. Finally, it self-destructs in a pyrotechnic effect.
