 In short, yes, you can. There are two ways:
-* 1. Fully unwrap your scene in your modeling package before baking (not individual objects, but the whole scene, in one or multiple atlases). Group objects sharing each atlas under a common parent object. Put[[Manual#Bakery_Lightmap_Group_Selector|Lightmap Groups]] with '''Original UV''' mode to  these parent objects. Bake. This way the resulting lightmaps will have 100% original UV match. You can then get the baked .hdr textures and use them anywhere.

 * 2. If you can't pre-unwrap the whole scene, then you'll need to export the updated geometry with new UVs. Simply using a common FBX exporter won't work, because Unity also has a per-renderer [https://docs.unity3d.com/ScriptReference/Renderer-lightmapScaleOffset.html UV scale/offset] for lightmaps which is not exported. The purpose of this is to save memory: multiple instances of the same mesh can have the same UV buffer, but apply this scale/offset in the shader instead. To properly export the scene, you'll need to generate new unique meshes with scale/offset baked into their UV buffers. There is a [[Community_extensions#Make_Exportable|Make Exportable script]] to do that if you want.

+===What about mixed lighting?===
 Yes! Bakery supports combining real-time direct lighting with baked indirect, as well as [https://docs.unity3d.com/Manual/LightMode-Mixed-Subtractive.html subtractive] and [https://docs.unity3d.com/Manual/LightMode-Mixed-Shadowmask.html shadowmask] modes.

 You can ship games with Bakery lightmaps on any platform. But for using Bakery you will need a 64-bit Windows (7+) machine with a Nvidia (6xx or newer) card. Check [[Manual#System requirements|system requirements]].

 Current Unity edition of Bakery is for editor use only, i.e. baking logic only works on editor side, and builds can only display baked lightmaps, not generate new ones. Technically baking can be invoked at runtime, but there is no finished/documented API for that. You would also have to manage scene exporting, atlas packing and texture importing manually. Runtime baking would also require a modern Nvidia GPU from your players and it would be up to you to ensure that builds don't go out of memory. Overall, it's doable, but with a lot of coding and it is not the best solution to the problem. If you are still interested in trying to bake something at runtime, you can contact me for C++ API headers.
