Hi all!
I’m creating a VR standalone oriented game (no need of a PC to run the application) for meta quest 3, and I’m encountering serious problems to be able to build light. Initially, my map was semi-open and the size of the landscape I used was quite large (several kilometers in size). My idea was to divide the huge map into different zones so that when you transition from one to another the rest of the map would be hidden in sublevels, but when I decided I wanted to venture into making the game work only with the VR glasses I discarded the idea and reduced the size of the playable areas. You can still visit all the locations but adapted in size and loading a new level when you reach the end. My problem comes from the fact that, being a standalone game, I think I need to resort to built light almost 100 percent, but when I try to build the light on the landscape this is full of artifacts and bugs. I am almost 100% sure that it is the fault of the lightmap resolution, but I am not able to find a way to adjust it because if it is at acceptable levels artifacts are generated but if I raise it to a level where they disappear, my built data file weighs several GB, which is unacceptable.
I have tried resizing the landscape, deleting the spaces I don’t use anymore now that the map is smaller and everything I can think of but it doesn’t seem to help.
Even leaving only one section, it still comes out blue in the debug tool.
Deep inside me, I have the feeling that the problem comes from the fact that the original landscape was huge and that no matter how much I delete the lightmaps they are adapted to the original size, but deleting the landscape would be wasting a lot of work and I don’t really know enough about landscapes and vr optimization to know if the problem lies there or if there are other solutions. Any ideas?
Other than that, I’d appreciate any advice you can give me on optimizing for vr, because as much as I’ve trimmed the game it’s still ambitious to run in standalone. Thanks everyone in advance!
