attaching a vertex buffer object to a vertex array object

Question

I am trying to attach a vbo to a vao. However I only get it to work the "old" way:

bind vao
bind vbo
glVertexAttribPointer(...)
glEnableVertexArrayAttrib(...)
unbind vbo
unbind vao

Now I want it to implement the new bindless way, I tried it like this:

glVertexArrayAttribFormat(...);
glVertexArrayVertexBuffer(...);
glVertexArrayAttribBinding(...);

However then I only get a black screen.

Attaching the index buffer object to the vao works though:

glVertexArrayElementBuffer(...);

What am I missing?

Answer 1

Seems like I was missing

glEnableVertexArrayAttrib(...)

Thus, the correct replacement would be

glEnableVertexArrayAttrib(...);
glVertexArrayVertexBuffer(...);
glVertexArrayAttribFormat(...);
glVertexArrayAttribBinding(...);

And don't forget to set the stride in glVertexArrayVertexBuffer(...), it should not be 0!
