#lockdown Nick.Penwarden #rb none ========================== MAJOR FEATURES + CHANGES ========================== Change 3232283 on 2016/12/13 by Ben.Woodhouse D3D12 - downgrade root signature size warning to a log following a discussion with Microsoft. There's not much we can actually do about it, and it's not relevant to all hardware #jira UE-36999 Change 3232641 on 2016/12/13 by Mark.Satterthwaite - Eliminate redundant state changes in MetalRHI in the state cache. - Add a new debug level for setting buffers to nil prior to calls to set*Bytes so that the tool doesn't display incorrect data. - Make testing for validation & statistics features use the same EMetalFeatures API as everything else for consistency. - Cache the fallback depth-stencil texture in the state cache and ignore it for determining whether a pass can restart - if we are using this texture its contents are worthless anyway. Change 3232661 on 2016/12/13 by Mark.Satterthwaite Re-enable Metal SM5 & DFAO/DistanceFieldShadowing on Intel for 10.12.2 or later. Change 3232759 on 2016/12/13 by Ben.Woodhouse Fix memory leak on XB1 when calling GPURealloc with count of 0, suggested on UDN https://udn.unrealengine.com/questions/326660/gpurealloc-leak.html Change 3232803 on 2016/12/13 by Ben.Marsh Add UT to the populate DDC job, and cook UT and Fortnite for Mac as well. Change 3232836 on 2016/12/13 by Ben.Marsh Split cooks to populate DDC into separate nodes for each platform. May help to reduce number of timeouts on remote VMs. Change 3232974 on 2016/12/13 by Rolando.Caloca DR - Refactor common code to UWorld::RecreateScene #jira UE-36719 PR #2824 Change 3232976 on 2016/12/13 by Ben.Marsh Add missing dependency on tools node for Mac cooks. Need to compile SCW first. Change 3233289 on 2016/12/13 by Olaf.Piesche Fixing potentially broken spot/point light fade with old content; initialize new properties properly Change 3233811 on 2016/12/13 by Mark.Satterthwaite Fix compiling QA-Material tessellation shaders that don't need to emit from Hull or sample in Domain the HSOut buffer which was confusing MetalBackend. Change 3233854 on 2016/12/13 by Mark.Satterthwaite More information about texture type validation errors in Metal. Change 3234650 on 2016/12/14 by Rolando.Caloca DR - vk - Fix bad aspect on depth cubemaps Change 3234651 on 2016/12/14 by Rolando.Caloca DR - vk - Fix for 32 bit crash on dump layer Change 3234813 on 2016/12/14 by Guillaume.Abadie Fixes texture mask static lighting when using GBuffer selective outputs. #jira UE-39527 Change 3235047 on 2016/12/14 by Uriel.Doyon Refactored HLOD texture streaming strategy to separate forced load from visibility. Added an incremental update in the last stage of the texture streaming update load to clear any pending work. Added an option "All" to the "BuildMateriaTexturelStreamingData" command to force rebuild everything. Change 3235317 on 2016/12/14 by Uriel.Doyon Removed timed primitives in the texture streaming since it was not used and there is now a fallback implementation in UPrimitiveComponent::GetStreamingTextureInfo. Change 3235431 on 2016/12/14 by Rolando.Caloca DR - Fix for Vulkan drawing black Change 3236788 on 2016/12/15 by Mark.Satterthwaite Fix 10.11.6 support (aka -nometalv2): the stencil view workaround necessitates a mid-render blit and the way things were setup resulted in the HasValidRenderTargets assert firing. Refactored the code to separate the concept or valid render-states in the cache from active render-states in the render-pass. Now it works as intended and will be needed for 4.15. Change 3236850 on 2016/12/15 by Mark.Satterthwaite Make changing the Metal Shader Version project setting prompt the user to restart for the changes to take effect. #jira UE-39801 Change 3237002 on 2016/12/15 by Benjamin.Hyder submitting updated TM-Shadermodels map Change 3237312 on 2016/12/15 by Rolando.Caloca DR - Change more macros to lambdas Change 3237394 on 2016/12/15 by Mark.Satterthwaite Add Metal-specific permutations of TBasePassHS - they affect the C++ definition on all platforms but are only cached or used on Metal - because the way we compile the combined VS+HS tessellation stage requires that the combined VS + HS HLSL code references the same resources, otherwise we get incorrect resouce bindings and subsequently fail to render properly. Long-term the Metal tessellation code will need to be refactored so that the vertex shader stage is emitted as a separate shader from the hull shader stage as this but will keep cropping back up and continue to complicate the engine. #jira UE-39799 Change 3237490 on 2016/12/15 by Daniel.Wright Fixed ULandscapeComponent::GetUsedMaterials Change 3237597 on 2016/12/15 by Ben.Woodhouse Disable timestamp queries on pre-Maxwell nvidia hardware. Local testing suggests that this is the major cause of instability in the UE4.14 release. It's possible that we could be more targeted by only excluding Fermi and older hardware, but identifying fermi hardware by device ID is difficult in practice, since the range overlaps with Kepler. Change 3237654 on 2016/12/15 by Daniel.Wright Non-editor compile fix Change 3238229 on 2016/12/16 by Rolando.Caloca DR - Remove ExcludeRect from inner RHI Clear methods; ensure will happen if trying to use it Change 3238236 on 2016/12/16 by Rolando.Caloca DR - Compile fixes Change 3238280 on 2016/12/16 by Marc.Olano Small optimization to Lanczos-3 upsample shader code. Change 3238321 on 2016/12/16 by Rolando.Caloca DR - Compile fix Change 3238331 on 2016/12/16 by Rolando.Caloca DR - compile fix Change 3238495 on 2016/12/16 by Marc.Olano Replace TEA random number generator with PCG. Was only used in #if-disabled reference rendering, but ldoes make better quality reference rendering when enabled. Change 3238496 on 2016/12/16 by Marc.Olano Tone mapping fix for OR-31752, cherry picked from Orion 3208273 Assumption that green is approximates luminance fails on red/blue HDR content, resulting in ugly black artifacts. Go back to luminance. Change 3238520 on 2016/12/16 by Rolando.Caloca DR - CIS Fix Change 3238571 on 2016/12/16 by Rolando.Caloca DR - CIS fix Change 3238605 on 2016/12/16 by Daniel.Wright Sharing IndirectLightingCacheTextureSampler samplers Change 3238626 on 2016/12/16 by Daniel.Wright Ray Traced Distance Field Shadow optimizations * Tighter light space tile culling * Skip ray marching pixels before the RTDF cascade near distance, or further than the cascade far distance * Depth bounds test on upsample * Created FLightTileIntersectionParameters for encapsulation of light tile culling functionality * RTDF shadow time went from 1.8ms -> .8ms and 3.1ms -> 1.2ms in FortGPUTestbed on 7870 with these changes Change 3238652 on 2016/12/16 by Rolando.Caloca DR - RHI clear methods no longer have an ExcludeRect, use DrawClearQuad functions instead Change 3238855 on 2016/12/16 by Rolando.Caloca DR - Added FRHITexture2D GetSizeXY Change 3238881 on 2016/12/16 by Rolando.Caloca DR - CIS fix Change 3239008 on 2016/12/16 by Arne.Schober DR - Fixing accidently returning a stackpointer in EnqueueRenderCommands Change 3239012 on 2016/12/16 by Arne.Schober DR - missing file Change 3239255 on 2016/12/17 by Rolando.Caloca DR - Remove shader clears from D3D11 Change 3239690 on 2016/12/19 by Rolando.Caloca DR - vk - Misc fixes from 1.0.37.00 SDK warnings Change 3239964 on 2016/12/19 by Rolando.Caloca DR - Fix click on editor not showing selected Change 3239995 on 2016/12/19 by Rolando.Caloca DR - Enable dist field on GL4 & Vulkan SM5 Change 3240162 on 2016/12/19 by Daniel.Wright Added EnableDepthBoundsTest / DisableDepthBoundsTest to RHIUtilites to share some common code Change 3240163 on 2016/12/19 by Daniel.Wright Distance field self shadowing controls for hiding world position offset self-shadow artifacts * Removed static mesh build settings DistanceFieldBias, which shrunk the distance field, breaking AO and shadows * Added DistanceFieldSelfShadowBias, which prevents occlusion close to the surface only, maintaining shadows on the ground and AO on the ground Change3240271on 2016/12/19 by Daniel.Wright Use 16 bit indices for distance field objects culled to tiles, when 16 bit will be enough.

Make sure dbuffer targets are bound if we're rendering mesh decals #jira UT-6891 #jira UE-39842 Change 3249721 on 2017/01/06 by Marcus.Wassmer Remove final references to non-existent Niagara data Change 3249742 on 2017/01/06 by Marcus.Wassmer Fix missing GPU particles on Mac. Pointers getting reused is causing the blendstate equality operator to fail. Simple workaround until we have time for a proper fix. [CL 3249983 by Marcus Wassmer in Main branch]
