As for the new Audio Engine, I noticed in Aaron’s demo at GDC he was using an envelope to drive materials.
Are there new Material Nodes available for this or is this purely a Blueprint/C++ implementation? I made a frequency spectrum analyzer in 4.15 with C++, but it relies on storing compressed bulk data of the original .wav as an asset. Being able to read from sound-cues in real time would be nice!
EDIT: Totally gonna abuse the volumetric particle feature… Can these special particles also be driven with textures?
