1. Create an IBakeInputRuntime and fill it with the RadSystemCore and InputWorkspace of each Enlighten system.
2. For each Enlighten system, create an IBakeInputSystem using all the Radiosity objects of the Enlighten system. This is required later in the process in order to fit the Enlighten lit instances to the bake system instances. Set the resolution of the IBakeInputSystem to the resolution of the Enlighten lightmap via an IBakeInputProperties object passed to the IBakeInputSystem::SetBakeProperties method.
3. For each Enlighten system, call IBake::CreateRuntimeLighting to create an IBakeRuntimeLighting from:
   1. the IBakeInputSystem that you just made
   2. the IPrecompSystemDuster
   3. the IPrecompPackedSystem
   4. the global IBakeInputLighting
4. For each runtime lighting you made:
   1. For each bake system representing the output lightmaps:
      1. Call IBake::UpdateRuntimeLighting to apply the light and albedo information for each bake system to the Enlighten system.
   2. Call IBake::FinaliseRuntimeLighting
5. Call IBake::RunEnlightenSolver; this takes all the information and spins a small Enlighten Runtime until the lighting values settle. This is run only once as it contains information about every system in the bake.
6. For each bake system, call IBake::BakeSystemIndirect and extract the indirect lighting from the IBakeOutputSystemIndirect it creates. Optionally pass in a BakeSystemResource object and a IBakeInputRayOriginPositions to be able to enable visibility-aware upsampling with the identically named baking property.
