I don’t know if someone asked for this before me. In my pipeline I use an hybrid system: datasmith for architectural elements and non repetitive elements modeled in Revit and csv data reading for positioning my blueprint actors as their counterparts are in Revit for library ones (laboratory analyzers, benches, fixtures, luminaries and so on).
For Datasmith importing it would be fine to have some kind of voxelization option for big walls, ceilings and floors. I think so to avoid 4K lighmaps for these elements that as well in many circumstances 4K doesn’t give enough quality. For example, if elements bigger than a 10 meters cube are encountered, then they would be divided in so 10 meters voxels as needed, and convenient lightmapped. This is not only good for lightmapping calculations but also for distributing meshes for calculations on swarm agents in a balanced manner.
What do you think?. I know a studio that is doing something similar in house plugin.
