I want to render to a cubemap without using the geometry shader for layer selection.
I have read that subpasses might be helpful but I would need to configure the subpass attachments to select the proper layer.
But I have only very limited knowledge about the entire proceedings.
As I understand the dependencies:
I create a commandbuffer using a renderpass and framebuffer
the framebuffer knows about the same renderpass AND about the view to the render target
the view and the framebuffer contain knowledge about a layer count
the views image shoul contain the same number of layers
The view also allows me to select a baseArrayLayer to which I can write.
Now, I would have hoped to find som layer correspondece during subpass creation, but I fail to see any connection.
I hope for some help and explanation or a statement on whether what I try to do makes sense.
