I dont know if this is possible or if I'm misunderstanding what the spherical harmonic data sets are, but can we combine these maps together?
For instance, lets say I have mapped a warehouse, then I create a new map for a box, and a new map for a trash can, etc., etc. Each of these additional pieces of geometry have separate spherical harmonic maps. So now I have this library of objects "props" that have spherical harmonic maps for them.
Now, I position these additional props inside the warehouse, and there individual maps are added/summed to the warehouse map.
Now for GI, instead of Vray needing to calculate what's "there", it now has this summed spherical harmonic map with all the geometry and their surface properties. I can swap different props in and out of the scene, animate their movement and the GI will just work by updating the summed spherical harmonic map.
