Hey Necrophobic! It’s been a long time. 
I hacked LPV emissive to work last night, so my emissive bricks now light up the world:
However, the ambient occlusion value I use to prevent the sky ambient from affecting indoor areas also prevents those areas from being lit up by indirect and emissive lighting from the LPVs. I’m trying to figure out if there’s a good way to work around this, or if I just need to do an ambient occlusion style CPU-lighting hack.
