It has been a little over a year since I last covered architectural visualization in Unreal Engine 4, and quite a lot has happened in the meantime. One of the main trends this year is the transition from pre-rendered sequences to interactive virtual reality experiences, made possible by the availability of affordable head-mounted displays, such as the HTC Vive and Oculus Rift.
On the Engine side, several features were added that may be interesting for ArchVis projects. In 4.12 we released support for real-time planar reflections and clear coat shading models that work great for shiny surfaces. In 4.14 we added a forward shading renderer with MSAA. It is particularly well suited for VR applications due to its performance characteristics for stereoscopic rendering. In 4.16 we introduced volumetric fog, which some users already started to utilize for impressive ambient lighting effects.
Sequencer has also seen some great improvements over the course of the last twelve months, and we have another major feature update scheduled for the upcoming 4.17 release. Many users asked for better integration between Media Framework and Sequencer for rendering ArchVis videos with embedded movies. This is something we’re still working on.
