Storage buffers
You use Storage buffers for that. Storage buffers are usually slightly slower than uniform buffers, but they can be much, much bigger. If you want to stuff your entire scene into one buffer, you have to use them. Make sure to profile it to know the performance. With storage buffers, you can have an unsized array in a shader with whatever data
