I’ve decided to have the scene without a roof (Like a level in a isometric RPG) so I was unsure how to implement light portals. I tried with a large one from above but saw no improvements and even increased my render time by 50%! I disabled them now and will read up on usage.
Regardless, I updated the scene with the new LOD B building blocks. Went with a curvier design for the pieces and the scene already looks so much better than LOD A!
I just found this because I posted something with similar key words (“Medieval cellar”), and I love it! I checked out all your posts about the project. I really like how your pieces fit together and your textures as well. Nice work!
