OMG you're right. Those images way to big. I resized them and tested with RX580 machine and it worked. If you have time can you try the new texture fix version? EnchantedGalleryTextureFixWindows.zip

It worked, this time! I think there's still room for progress on a few assets, because I had a huge lag spike when the animal spawned and another one when it arrived in the gallery (the photos I guess?). But if you can shrink those assets I bet it would even be possible to export for Quest and Pico.
Anyway, it's beautiful, and the 3D photo effect is stunning!
