Secondary command buffer for rendering in vulkan

Question

Is it possible to make the rendering happen in the secondary command buffers? For example, there are 3 primary buffers and they call secondary buffers, which in turn render? I want to make a simple Manager that allows you to add and remove new objects on the screen.

Answer 1

Yes. And when using secondary command buffers and the VK_SUBPASS_CONTENTS_SECONDARY_COMMAND_BUFFERS flag for your renderpass (see VkSubpassContents) you actually have to put all rendering commands into secondary command buffers that are called from within the primary command buffer using vkCmdExecuteCommands.
