From https://registry.khronos.org/OpenGL/extensions/ARB/ARB_shade...:

   (3) "Do we allow arrays of shader storage blocks?

        RESOLVED:  Yes; we already allow arrays of uniform blocks, where each
        block instance has an identical layout but is backed by a separate
        buffer object.  It seems like we should do this here for consistency.

PS: You could also access data through bindless textures, though you would need to deal with ugly wrappers to unpack structs from image formats.

Do you have an example for that? I can't find any.

Regarding bindless textures, they're really ugly to use. Shader buffer load is so much better, being able to access everything with simple pointers.

Here's some code: https://github.com/KhronosGroup/OpenGL-API/issues/46 But yeah, GL_MAX_VERTEX_SHADER_STORAGE_BLOCKS limits usefulness of that.

I wanted to say that with some compiler hacking it should be possible to lower SPIR-V using GL_EXT_buffer_reference into bindless image loads, but SPIR-V doesn't have standardized bindless texture, duh!
