This has several benefits:
- Transparency sorting issues inherent to alpha blending no longer occur.
- Alpha hash materials can now cast shadows (also works with
GeometryInstance3D Transparency's property for alpha hash materials).
- Higher performance.
Initial TAA support based on the implementation in Spartan Engine.
Motion vectors are correctly generated for camera and mesh movement, but there is no support for other things like particles or skeleton deformations.
* Map is unnecessary and inefficient in almost every case.
* Replaced by the new HashMap.
* Renamed Map to RBMap and Set to RBSet for cases that still make sense
(order matters) but use is discouraged.
There were very few cases where replacing by HashMap was undesired because
keeping the key order was intended.
I tried to keep those (as RBMap) as much as possible, but might have missed
some. Review appreciated!
Didn't commit all the changes where it wants to initialize a struct
with `{}`. Should be reviewed in a separate PR.
Option `IgnoreArrays` enabled for now to be conservative, can be
disabled to see if it proposes more useful changes.
Also fixed manually a handful of other missing initializations / moved
some from constructors.
The default shadow material was used for depth rendering disregarding the cull mode of the original material. This commit adds a check so the default shadow material is only used when the original material has back-face culling.
Fixes a regression introduced by the color pass flags rework. The various rasterizer state structs were not being reset for each flag combination, which meant some state changes were wrongly applied to some flag combinations.
The validation layers were complaining that we use DEFAULT_RD_TEXTURE_WHITE (which is RGBA8) in places where it's sampled as a depth texture. This commit adds the new default texture DEFAULT_RD_TEXTURE_DEPTH and uses it where needed.
This commit removes a lot of enum values related to the color render pass in favor of a new flag-bases approach. This means instead of hard-coding all the possible option combinations into enums, we can write our logic by checking a bit-mask.
The changes in rendering_device_vulkan.cpp add support for unused attachments. That means RenderingDeviceVulkan::framebuffer_create() can take null RIDs in the attachments vector, which will result in VK_ATTACHMENT_UNUSED entries in the render pass.
This is used in this same PR to establish fixed locations for the color pass attachments (only color and separate specular so far, but TAA will add motion vectors as well). This way the attachment locations in the shader can stay the same regardless of which attachments are actually used.
Right now all the combinations of flags are generated, but we will need to add a way to limit the amount of combinations in the future.
* Changed syntax usage for RD::Uniform to create faster with a single RID
* Converted render pass setup to use this in clustered renderer to test.
This is the first step into creating a proper uniform set cache system to simplify large parts of the codebase.
- Add 2D and 3D in timestamp names when needed to avoid ambiguity.
- Use present tense in all render timestamp names.
- Add a space after ">" (begin) and "<" (end) symbols.
- Remove redundant "End" in render timestamp names (indicated by "<").
`smoothstep()` avoids the sudden transparency jump when entering or
leaving an object's alpha fade margin distance. This in turn helps
make opacity transitions less noticeable to the player, as it's
less likely to catch the player's eye.
