#lockdown ben.marsh ========================== MAJOR FEATURES + CHANGES ========================== Change 2733540 on 2015/10/19 by Daniel.Wright@Daniel.Wright_G5038_RenderingStream Capsule shadows * Capsule shadows excel at extremely soft area shadows caused by a large light source angle, but don't support accurate self-shadowing * Artists can setup a physics asset containing Spheres and Sphyls (capsules) for a skeletal mesh that will be used to represent the mesh's occlusion * These shapes can then be used for direct shadowing (bCastCapsuleDirectShadow) on a skeletal mesh component, whose softness depends on the light source angle / radius * The shapes can also be used to create an indirect shadow (bCastCapsuleIndirectShadow), whose direction and softness is derived from the precomputed sky occlusion (stationary sky light) or primary indirect lighting (static sky light) * Capsule shadowing is computed at half res and uses tiled deferred culling for efficiency - only implemented for PC SM5 + PS4 so far * Shadowing of movable skylights is not yet supported Change 2735460 on 2015/10/20 by Uriel.Doyon@uriel.doyon_office_data Basepass drawlist are now merged within a single drawlist. Lighting policy parameters are now accessed through a uniform buffer. Changed the global resource initialization so that InitRHI now comes before InitDynamicRHI #codereview nick.penwarden Change 2744741 on 2015/10/28 by Nick.Penwarden@nickp_streams Remove unused RHI methods: RHIIsDrawingViewport RHIGpuTimeBegin RHIGpuTimeEnd Made default/empty versions of these calls and removed stubs from RHIs that don't use them: RHISuspendRendering RHIResumeRendering RHIIsRenderingSuspended Change 2745714 on 2015/10/28 by Daniel.Wright@Daniel.Wright_G5038_RenderingStream Lighting channels - each component and light can choose from 3 channels * Primitives output their channel mask to stencil during the base pass, the masks are copied to a texture after the base pass, deferred lighting passes compare the primitive mask against the light's mask * Dynamic shadow casting also respects the channels * Only works on opaque materials, direct lighting, dynamic lighting * Not implemented for tiled deferred atm * This will replace CastsShadowsFromCinematicObjectsOnly in the future #rb Martin.Mittring Change 2746243 on 2015/10/29 by Marcus.Wassmer@Marcus.Wassmer_DevRendering_New First pass at separate Async Compute Context #codereview Lee.Clark,Daniel.Wright #rb Gil.Gribb Change 2746989 on 2015/10/29 by Martin.Mittring@Martin.Mittring_Z3941_Dev_Rendering Removed a lot of complexity of the skeletal mesh motionblur code (better for multithreading, simpler, faster) but going from one large buffer to per mesh buffers. Upload of bones only needed once. * GPUSkinCache didn't even work before (in this branch) * tested BasePass velocity * tested split screen * tested editor pause * matinee camera cut (no need, invalidates velocity) * tested CPU Skin? (never has motionblur) * tested CreateSceneProxy (recreation is prevented in CreteSceneProxy unless bone count changes) * test ES2 -featureleveles2 #rb: Rolando.Caloca Change2750734on 2015/11/02 by Uriel.Doyon@uriel.doyon_office_data Embree integration into Lightmass Can be enabled through Lightmass.ini [DevOptions.StaticLighting]bUseEmbree. Also [DevOptions.StaticLighting]bVerifyEmbree will compare ray casting results. Only usable on Win64 with this submit. #review daniel.wright Change 2752730 on 2015/11/03 by Martin.Mittring@Martin.Mittring_Z3941_Dev_Rendering added SSAO CS version, can be enabled with r.AmbientOcclusion.Compute 1 Not optimized yet #rb:Olaf.Piesche Change 2752766 on 2015/11/03 by Daniel.Wright@Daniel.Wright_G5038_RenderingStream Lightmass solver quality improvements * IndirectLightingScale is no longer applied to photons, avoids splotchy artifacts when using small scales * New 'Lightmass Portal' actor / component which tells the solver where to look for significant lighting. When lighting with a Static Skylight only, in a mostly indoor environment, setting up these portals is the only way to get high quality. * Skylight bounce lighting is now much more accurate and leverages adaptive sampling * Fixed a bug that effectively disabled adaptive sampling on high IndirectLightingQualities * Shadow penumbras are also improved by IndirectLightingQuality * Texel debugging is now a cvar 'r.TexelDebugging', instead of requiring a full recompile Change 2754018 on 2015/11/04 by Uriel.Doyon@uriel.doyon_office_data Quad Complexity ViewMode (PCD3D_SM5 only). Shader Complexity with Quad Overhead ViewMode (PCD3D_SM5 only). Require ShaderComplexity ViewMode & Show.Visualize.QuadOverhead #review brian.karis Change 2754760 on 2015/11/04 by Martin.Mittring@Martin.Mittring_Z3941_Dev_Rendering improved SSAO quality (less high frequency noise) to avoid TemporalAA smearing Change 2756308 on 2015/11/05 by Rolando.Caloca@rolando.caloca_T3903_S DevRendering - Enable removing unused outputs on PS4 shader pipelines, disable by default removing unused on D3D (toggable with r.D3DRemoveUnusedInterpolators) #codereview Marcus.Wassmer Change 2757063 on 2015/11/06 by Simon.Tovey@Simon.Tovey_Dev Submitting pull request from user Pierdek. Early out of particle collision module update if there are no active particles. #github #1614 Change 2757340 on 2015/11/06 by Gil.Gribb@Gil.Gribb_Z2439_Dev-Rendering UE4 - Fixed the experimental r.RHICmdBalanceParallelLists 2 mode and renabled it for orion. Change 2757343 on 2015/11/06 by Gil.Gribb@Gil.Gribb_Z2439_Dev-Rendering UE4 - Added a path so that texture streaming can avoid flushing the RHI thread. Change 2757985 on 2015/11/06 by Daniel.Wright@Daniel.Wright_G5038_RenderingStream Added new PrimitiveComponent setting bSingleSampleShadowFromStationaryLights * When enabled, shadowing of a movable component from a stationary directional light will come from the Volume Lighting Samples precomputed by Lightmass * This provides essentially free on/off shadow receiving on dynamic objects, with a fade over time between states * Lighting has to be rebuilt once for this to work #rb Rolando.Caloca Change 2759058 on 2015/11/09 by Gil.Gribb@Gil.Gribb_Z2439_Dev-Rendering UE4 - Dynamically set stream source to avoid creating a separate drawing policy for each static mesh with vertex colors. #rb Daniel.Wright Change 2760523 on 2015/11/10 by Uriel.Doyon@uriel.doyon_office_data Enabled Embree by default #review daniel.wright ========================== ALL CHANGELISTS ========================== Change 2720123 on 2015/10/07 by Rolando.Caloca@Rolando.Caloca_T4688_5331 'Dev-Rendering - 'integrate' Tem' Change 2721682 on 2015/10/08 by Gil.Gribb@Gil.Gribb_Z2439_Dev-Rendering 'UE4 - Eliminated a fatal error ' Change 2721815 on 2015/10/08 by Rolando.Caloca@Rolando.Caloca_T4688_5331 'Dev-Rendering - Fix crash exiti' Change 2724755 on 2015/10/12 by Rolando.Caloca@Rolando.Caloca_T4688_5331 'Dev-Rendering - D3D12 Fix Tier' Change 2724781 on 2015/10/12 by Rolando.Caloca@Rolando.Caloca_T4688_5331 'Dev-Rendering - D3D12 Fix offse' Change 2728317 on 2015/10/14 by Rolando.Caloca@Rolando.Caloca_T4688_5331 'Dev-Rendering - hlslcc - Fix fo' Change 2729170 on 2015/10/14 by Chris.Bunner@Chris.Bunner_Dev_Stream 'Force Lightmass volume sample g' Change 2732131 on 2015/10/16 by Martin.Mittring@Martin.Mittring_Z3941_Dev_Rendering 'fixed resource transition issue' Change 2732218 on 2015/10/16 by Martin.Mittring@Martin.Mittring_Z3941_Dev_Rendering 'minor code cleanup ' Change 2733533 on 2015/10/19 by Daniel.Wright@Daniel.Wright_G5038_RenderingStream 'Clear stencil to 0 after decals' Change 2733540 on 2015/10/19 by Daniel.Wright@Daniel.Wright_G5038_RenderingStream 'Capsule shadows * Capsule shado' Change 2733546 on 2015/10/19 by Daniel.Wright@Daniel.Wright_G5038_RenderingStream 'Light shaft targets are only al' Change 2733602 on 2015/10/19 by Uriel.Doyon@uriel.doyon_office_data 'Decals not writing to Normal ca' Change 2733627 on 2015/10/19 by Marcus.Wassmer@Marcus.Wassmer_DevRendering_New 'Fix for transition ensure.
