: If you are shipping DLC, consider using ProjectSettings.load_resource_pack() to load .pck or .zip files exported directly from Godot for better compression and faster loading.
: Data stored in Video RAM (VRAM). This is what you assign to a Sprite2D or a MeshInstance3D for fast rendering. 4. Best Practices for Texture Management
: Godot will automatically detect new images (PNG, JPG, BMP) and import them as Texture2D resources. 2. Loading ZIP Archives at Runtime (for Mods/DLC)
: Keep textures under 16384×16384 pixels, as larger files may fail to load on many graphics cards.
: Convert that buffer into an Image , then into an ImageTexture .
