I had a lot of hope in solution too… but from what I’ve tried LPV are the way to go if you want fully dynamic GI but they tend to crash in packaged game and it doesn’t work with opengl/metal/vulkan (only gnm and dx11). .unrealengine.com/latest…mes/index.html .
I hope Epic will not stay on lightmass stuff, semi static solution is very slow in term of production (the building take too much time and have too much failure cases) and bring to much limitation in term of interactivity IMO. =/
