In the first version, I did a procedural generation of striped images.
In the second version, I generated random images in XZ coordinates as the camera moved.
In the third version, I made the generation of images randomly glued on top of each other.
In the fourth version, I generated random images from chunks using XZ coordinates.
In the fifth version, I generated different images by chunks in XZ coordinates within LOD, deleting the previous chunks
In the fifth version, I generated different sets of images based on chunks in XZ coordinates
In the sixth version, I generated images with different sizes based on chunks in XZ coordinates.
A version with sets of different images in a line of X with different image sizes.
FINALLY! A version with different sets of tiles of different image sizes.
All that remains is to make a version with different sets of tiles of different sizes with a seed so that the same set of random tiles is always generated.
