Hello, thank you very much for the reply – it helped me understand the process of lightbaking even more. The video tutorial was also great. I eventually managed to achieve what I was trying. The addon BakeLab helped me a lot, especially with creating and assigning the materials. I ended up dividing my objects into 5 groups and using a separate baked material for each group. The baked images were pretty low-res due to the large number of faces on each image but it works.
