Big Area Lightmapping

Hello,

I am working on a racing game for mobile. I need to lightmapp it for keep a good optimization. Can anyone tell me how can i do a lightmap for big area in Unity 2017.3?

 

Good UVs, use the progressive lightmapper.

You'll have to be a bit more specific.

 

Is there any good settings like resulation settings or something? Track is about 3.5 KM long.

 

its too big area, you should decrease the size. or make 1 big textures for the all objects, like its should be diff+shadow in one map

 

Have resolution be really really low? Like start with 0. something and see how it goes?

 

Every time when I bake the scene it works then it show failed executing external process for bake visibility job

 

It is not possible now to make all object into one map.

 

Create the map in the modeling programs

 

or try exporting it out as obj
grouped by the same material (I think ObjExporter.cs does that)
