I have some CAD-Files/Machines which by interaction can be opened up and closed. Is there a way to bake Lightmaps for both states?
For now I built some pretty complex setup in Houdini which allows me to bake both states into a single map, but externaly baked AO and shadows just a workaround and good practice I guess…
FIrst I was thinking to bake the to objects separately in UE and merging them later.
But doing it like this, both objects would miss some shadows and AO.
To explain what I mean: imagine a house with a big roof and the roof could be hidden to look inside. If I would bake the house and roof separately to assemble them later, both objects would lack some AO and shadows they would cast onto each other.
The other way would be to use two completely different (open/closed) meshes/versions and switching them via blueprints, but I am not sure if that’s a good approach in terms of memory…
Some recommended looking into lightmap scenarios, but I did not fully understand how they are actually supposed to work and if they the right way.
Would be great if somebody could point me into the right directidirection.
