Bumping this because i am more or less in the same situation and i believe this will become a requested feature from several users, let’s see if there’s more interest in it.
By the way @Jungaea did you make any more progress on the shader you are working on? Seems a good step in the right direction! It would be great to have occlusion shadows as well (not self occlusion of course)… Would you be able to share your progress (if there’s any over the great info you already provided)? Not that i think i can help, being completely ignorant about shader programming, but have a colleague that might and well, we could surely make a use of it for the moment as we experiment on some photogrammetry locations we scanned. For now i’ll just try and follow your tips to get dynamic shadows in place. Thanks for sharing!
