After that i baked lightmaps and set my camera i hit play and all that i baked just dont want to be shown.
i seted parametr “use lightmaps” but they just dont want work. all types of baked lightmaps dont work.
found a “bug”.
i had a Combine Children (script) on objects. So every time i hit play, script start to batch object’s (script is on group of objects) and creating a Combine meshes, but in that case, i dont know why, Mesh Renderer option going to “off” position. So i see combined meshes only, which dont have a baked lightmaps. Strange thing - i dont have an Statik option for mesh combine (batching statik) but its starting to work in any case.
I saw that too - “Combine children” kills lightmaps. But I also found it wasn’t as good as the built in static batching, which doesn’t kill lightmaps – if you just mark your objects “static”, then unity will combine them for you, on the fly.
