I have a land area of a few city blocks imported into Blender 2.9 from Google Maps. It is many meshes, 1200 materials. I can Ctrl-J the meshes into a single mesh. Is it possible to bake the 1200 PNG files down to a single? If so, please direct me to a video or text tutorial demonstrating the process. Thank you.
I think that tutorial can be helpful for you: https://www.youtube.com/watch?v=XUkMY8Sp_AM.
