For a project like this: https://xrsrdesign.shapespark.com/sample_01/
I’m using .gltf model.
I’m learning about how to bake the light map. Can tell me some of the best software to bake light maps. And how can i load it into the scene?
You can bake light maps with Blender. It might not be “the best software” for doing this but it’s free.
I suggest you are looking for existing tutorials.
It’s recommended to export to glTF although you can’t include a light map. Meaning you have to load it separately and apply it to your asset.
