I have a static mesh that has 3 LODs, each LOD having 3 UV maps (it’s for mobile, so UV0 is for normal map, UV1 for diffuse and UV2 is for lightmaps).
I don’t quite understand what my Lightmaps settings should look like per LOD.
Each LOD has Lightmap Source and Destination index. By default my mesh LODs all have the same settings - source index is 0 and destination index is 3. What do source and dest. index stand for and what should I set their values to ?
Then there is Lightmap Coordinate Index in the “global” Static Mesh Settings, which is set to 2. What is this and what should it be set to? (I assume index 2 is what UV2 is; in which case it’s the correct value)
How do Lightmap Source and Destination index, and Lightmap Coordinate Index relate to each other ?
