Check gbuffer rendering status before setting blend mode for model material

SamuelCho
authored and
notimaginative
committed
Instead of checking gbuffer rendering to disable blend mode for models, check depth mode for ZBUFFER_TYPE_FULL instead.

SamuelCho
authored and
notimaginative
committed
Make sure to set material fill mode when building pipeline config.

Reduced transparency buffer alpha channel threshold to 0.75f. Slight clean-up of transparency geometry processing code.

SamuelCho
authored and
notimaginative
committed
Fixed corrupted transparency buffer geometry if number of indexed vertices exceed the unsigned short maximum. Restored the original alpha threshold for transparent geo.

Fixed incorrect viewport, scissor, and triangle winding order states when rendering shadow maps.

SamuelCho
authored and
notimaginative
committed
Fixed shadow maps unnecessarily starting the deferred rendering pass when it should instead be resuming either the swapchain or scene framebuffer render pass. Fixes shadows when rendering directly …

SamuelCho
authored and
notimaginative
committed
Color attachment initial layout for scene render pass load needs to be eShaderReadOnlyOptimal to match the scene render pass final layout.

SamuelCho
authored and
notimaginative
committed
Remember to update the state trackers with the current render pass and number of color attachments when resuming the scene render pass.

SamuelCho
authored and
notimaginative
committed
Set the expected initial layout back to normal for scene render pass load. Instead of using the load scene render pass after shadow maps, create a resume scene render pass.

SamuelCho
authored and
notimaginative
committed
colorRef.attachment for m_sceneRenderPassResume should be eColorAttachmentOptimal

SamuelCho
authored and
notimaginative
committed
Brought back the deferred render pass bindings after the shadow map pass.
