Fractured and simulated in Houdini, this sim of the Pyramid collapsing is used in both Ladder and Story Endings. It was brought into Unreal as a point cache for use in Niagara

Lightning FX for Pyramid. The system has two emitters throwing points to collide with the environment. Ribbons are drawn between the collision points to create lightning the collides with the environment

Every stage of the Pyramid has a "breathing" effect. Consisting of Niagara Systems and Materials, the timing is controlled with a central Material Parameter Collection

Smoke FX and Gold pouring. The smoke is a Niagara system with a smoke flipbook that was created in Houdini. This is the "High Quality" Gold that was simmed in Houdini and used in story renders. The level has a lighter-weight material effect.

This Plasma Ball was a fun blast from the past to make. It uses similar tech to the Pyramid lightning with particle positions constricted to a sphere

Hourglass rock streams. Consists of a Niagara system tied to a spline in a BP with a custom method of "pulling" the particles along with a force, rather than directly setting the position based on the path

Gear Select fountain. The water effect is an adapted system of the waterfalls used in Invasions. I coupled that with a system of splash meshes I simmed in Houdini.

I'm sure this is everyones favorite screen to see in Invasions. I simulated the glass shatter and pulled it into the engine as a point cache in Niagara
