The 360 environment is used as both a reflection and environment map, so a Trapcode animation is reflected perfectly onto an E3D Statue. The plugins look like they are seamlessy integrated and inhabit the same space in Ae.
Mettle SkyBox is an Ae script/plugin to generate 360 Reflection/Environment Maps (equirectangular, cubic cross, spherical). The Maps can be used as Environment/Reflection Maps in Ae, in 3D Apps, and are the right format for youtube 360, VR, Dome projections and Gaming. To find out more: mettle.com/product/skybox/
