Textures packing and lightmap for asset store?

Udjani

Hey, i read the submission guidelines but could not find answer for this questions.

1. If the asset is PBR is better to pack them or upload them separately? 

2. Making sure that lightmaps will work in every situation is not possible? Lets say that i want my model to have a 64x64 lightmap and i unwrap it accordingly to it, unity may change how the uv will be in lightmap atlas depending on the size/proportion of all assets?

1. Pack what? All the textures? Just add the asset to the package, Unity will do the rest.

2. Just make a clean layout for that asset, no overlaps or stretching, and filling the 0-1 space.

By packing i mean the albedo, roughness, occlusion etc. I know that i can pack Metal/smooth with occlusion, but was wondering if would be best to keep them separated.

Do whatever the shader requires, and use an uncompressed texture format. People can unpack if needed.
