Assembling multi-pass GPU frames requires coordinating render pass descriptions, attachment lifetimes, and per-attachment load/store semantics. You use a chainable API to construct passes via pass() and attachment() from a FrameCtx, wiring color/depth targets and execution together.

Handling MSAA resolve chains involves allocating transient color textures with specific sample counts and configuring resolve targets. You build a pass that renders a 4x MSAA scene into an offscreen attachment, then resolves it into a single-sample texture for downstream post-processing.

Conditional rendering in a frame graph is achieved by orchestrating pass content with .by_if(). This executes draw units inside a pass only when specific runtime conditions are met, allowing optional pass content without breaking the overall frame structure.

You need to configure load/store operations for GPU render passes whenever multiple passes share attachments or require specific clear behavior. Correct load/store semantics ensure transient textures are cleared or preserved accurately between passes, preventing visual artifacts and state errors.

Yes, the multi-pass frame builder supports fullscreen quad post-processing. You use the .by() method to render draw units inside a pass, enabling a final pass that consumes a resolved single-sample texture to apply post-processing effects into the final render target.
