Help With Project for money

Having reduced all my textures I thought I was in the clean. It appears that Just a few trees that I had from Megascans had a bunch of maps with 8196 px maps. I reduced them and everything works fine!

I have two questions if anyone can answer:

  1. Is there some literature on the memory limits for oculus quest 2? I intent to make several games for this platform and I’d like to understand deeper the memory limitations

  2. Is game launcher the only way to be sure that everything has been updated in your editor? I have come to realize that just saving everything is not enough to be sure that everything is updated.
