begin_secondary_commands()

CommandBufferID MayaFlux::Portal::Graphics::ShaderFoundry::begin_secondary_commands

(

vk::Format

color_format

)

Begin recording a secondary command buffer for dynamic rendering.

Parameters

color_format

Format of the color attachment (from swapchain)

Returns

Command buffer ID

With dynamic rendering, secondary buffers don't need render pass objects. They only need to know the attachment formats they'll render to.
