MAJOR FEATURES + CHANGES
==========================

Change 3028958 on 2016/06/27 by Ben.Woodhouse

	Fix for perf issue with GetSingleFinalDataConst

	This was caused by the LPV integration/switch to blendables. Now we cache the flag for the directionalocclusion in the LPV class. This reduces calls to GetSingleFinalDataConst on the blendable data (potentially slow), and makes things a bit cleaner and consistent.

	Tested in QAGame editor (with LPV enabled in ConsoleSettings.ini)

	#jira UE-26179

Change 3029401 on 2016/06/27 by Rolando.Caloca

	DR - More vk logging

Change 3029549 on 2016/06/27 by Uriel.Doyon

	Refactored "r.OnlyStreamInTextures" into "r.Streaming.FullyLoadUsedTextures", making it fully load every used textures, as an alternative to disabling texture streaming.
	New options "r.Streaming.UsePerTextureBias" that assign a  bias between 0 and MipBias to each texture in order to fit in budget.
	Fixed crash when disabling texture streaming.
	Fixed issue when disabling texture streaming that would make current loaded texture low res.
	New logic to prevent retrying to cancel a streaming request more than once.
	Pending load request of one extra mip will not be cancelled anymore.
	Changed UTexture2D from float to double. Also using FApp::GetCurrentTime() instead of FPlatformTime::Seconds().
	#jira UE-32197
	#jira UE-31102

Change 3029837 on 2016/06/27 by David.Hill

	Fixed Shutter SM4 not working when using compute shader eye-adaptation
	#jira UE-32443

	The default eye adaptation value was missing.

Change 3030039 on 2016/06/27 by Uriel.Doyon

	Fix for crash when landscape materials are used in the Texture Streaming Build.
	#jira UE-32196

Change 3030081 on 2016/06/27 by Uriel.Doyon

	Updated MaterialTexCoordScalesPixelShader to use PackedEyeIndex, preventing crash when building the map with stereo rendering enabled.

Change 3030401 on 2016/06/28 by Ben.Woodhouse

	Perf Monitor: Fix for perf warning due to cvar FindConsoleVariable being called too frequently. Tested in QAGame editor (DX11)
	#jira UE-31238

Change 3030607 on 2016/06/28 by Marc.Olano

	Random Number generators: fixed bug in TEA, added integer and float Blum-Blum-Shub. BBS is way cheaper for similar quality, suggest it for future use.

Change 3030627 on 2016/06/28 by Ben.Woodhouse

	Fix for warning. CVar naming scope clash (doesn't appear to happen in vs2015).

Change 3030809 on 2016/06/28 by Marc.Olano

	Noise shader function rename & perf improvement.

	Due to incorrect terminology in internet soruces, previous "Perlin" noise was not, in fact, Perlin noise. Now more accurately called "Value" noise. 6x perf improvement for value noise by changing random number function to BBS. Also updated instruction counts in UI tooltips.

Change 3030850 on 2016/06/28 by Marc.Olano

	Rename & redirect noise material enums. At some point these got switched around and no longer accurately described the noise options the selected. Redirect, so all existing content will continue to work as-is. Updated UDN docs to match.

Change 3030981 on 2016/06/28 by Rolando.Caloca

	DR - vk - More logging

Change 3031056 on 2016/06/28 by Marc.Olano

Change 3031441 on 2016/06/28 by Marc.Olano

	Use only float version of BBS shader rand function for ES2

Change 3031463 on 2016/06/28 by John.Billon

	#Jira UE-32020

Change 3031512 on 2016/06/28 by Zabir.Hoque

	Merging //UE4/Dev-Main@3032394 to Dev-Rendering (//UE4/Dev-Rendering)

Change 3032757 on 2016/06/29 by Uriel.Doyon

Change 3035577 on 2016/07/01 by Marc.Olano

	Tiling noise. Adds tiling option for gradient, gradient texture, and value noise in the noise material node. Tiling is more expensive, but allows noise functions to be baked into a seamless repeating texture.

Change 3035587 on 2016/07/01 by Ben.Woodhouse

	Fix for async SSAO bug (SSAO Async Compute results are used before the async job wait)

	#jira UE-32709

Change 3035618 on 2016/07/01 by Olaf.Piesche

	Alpha Coverage Preservation
	-Textures have a Alpha Preservation Vec4 property which dictates about much of that channel to preserve down the mip chain during mip generation.
	#Jira UE-31986

Change 3036041 on 2016/07/01 by Rolando.Caloca

	DR - vk - Fix for 32bit

Change 3036433 on 2016/07/01 by Rolando.Caloca

	DR - More vk logging

Change 3036935 on 2016/07/04 by Simon.Tovey

	Removing Data Objects

Change 3036942 on 2016/07/04 by Ben.Woodhouse

	Fix for decal rendering resource leak

	The cause was that FD3D11BoundRenderTargets doesn't support setting RTs sparsely. So if one element is NULL, it won't release the ones after it.

	The sparse RT layout happened as a result of a change back in October, which meant that GBuffers for decals could be set sparsely, dependent on whether the decal wrote to the normalbuffer

	This change adds support for sparsely bound rendertargets in FD3D11BoundRenderTargets.

	#jira UE-32602

Change 3037563 on 2016/07/05 by Chris.Bunner

	HLOD self-shadowing in baked lighting fix.

Change 3037640 on 2016/07/05 by Marcus.Wassmer

	DR - Fix touch pads not showing on Vulkan
	#jira UE-32062

Change 3038085 on 2016/07/05 by Chris.Bunner

	HLOD dynamic shadowing support.
	#jira UE-22627

Change 3038209 on 2016/07/05 by Rolando.Caloca

	DR - vk - Android compile fix

Change 3038644 on 2016/07/05 by Uriel.Doyon

	Added LerpRange that allows to lerp between two rotators without taking the sortest path.

Change 3038820 on 2016/07/05 by Uriel.Doyon

	Selecting streaming accuracy view modes will not automatically generate missing visualization data.

Change 3039332 on 2016/07/06 by John.Billon

	-Made MaxGPUSkinBonesCvar a FAutoConsoleVariableRef and moved it to mesh utilitles from console manager to fix a thread initialization problem.
	#Jira UE-31710

Change 3039454 on 2016/07/06 by Simon.Tovey

	Moved all Niagara files from Engine and UnrealEd to remove dependancies and increase compile times.
	Niagara is now 99.999% decoupled from engine and editor so development should be much streamlined.

	Plus a few other edits to remove Curves/DataObjects that I missed in last CL.

Change 3039517 on 2016/07/06 by Gil.Gribb

	Merging //UE4/Dev-Main@3039013 to Dev-Rendering (//UE4/Dev-Rendering)

Change 3039587 on 2016/07/06 by Rolando.Caloca

	DR - vk logging, submit counter

Change 3039603 on 2016/07/06 by Rolando.Caloca

	DR - Allow more samplers on GL4
	#jira UE-32628
	#jira UE-32744

Change 3039661 on 2016/07/06 by Daniel.Wright

	Fixed non-directional DFAO occlusion on specular 'r.AOSpecularOcclusionMode 0'
	Skylight occlusion tint now applies to specular
	Skylight occlusion tint on diffuse is now correctly affected by DiffuseColor

Change 3039960 on 2016/07/06 by Daniel.Wright

	Forward renderer initial implementation
	* Point and spot lights are culled to a frustum space grid, base pass loops over culled lights.
	* Light culling uses a reverse linked list to avoid a per-cell limit, and the linked list is compacted to an array before the base pass.
	* New cvars to control light culling: r.Forward.MaxCulledLightsPerCell, r.Forward.LightGridSizeZ, r.Forward.LightGridPixelSize
	* A full Z Prepass is forced with forward shading.  This allows deferred rendering before the base pass of shadow projection methods that only rely on depth.
	* Dynamic shadows are packed based on the assigned stationary light ShadowMapChannel, since stationary lights are already restricted to 4 overlapping.
	* GBuffer render targets are still allocated
	* Fixed several issues in parallax corrected base pass reflections - not blending out box shape, discontinuity in reflection vector, not blending with stationary skylight properly
	* Forward shading is now used for TLM_SurfacePerPixelLighting translucency in the deferred path
	* Notable missing features: shadowing of translucency, support for various translucency lighting modes, multiple blended reflection captures

Change 3040050 on 2016/07/06 by Daniel.Wright

	Added r.Shadow.WholeSceneShadowCacheMb, which defaults to 150, to limit how much memory can be spent caching whole scene shadowmaps

Change 3040160 on 2016/07/06 by Daniel.Wright

	Fixed tile artifacts in indirect capsule shadows from doing the scaled sphere vs tile bounding sphere intersection in the wrong space

Change 3040163 on 2016/07/06 by Rolando.Caloca

	DR - vk - More logging

Change 3040257 on 2016/07/06 by Daniel.Wright

	Skylights aren't captured until their level is made visible- fixes the case where skylights capture too early

Change 3040316 on 2016/07/06 by Daniel.Wright

	PerObject shadows from point / spot lights do the light source pull back based on subject box size, not subject radius, since the box is used to find a valid < 90 degree projection.  Fix from licensee

Change 3040361 on 2016/07/06 by Daniel.Wright

	Fixed TexCreate_UAV being used on translucency volume textures in SM4

Change 3040402 on 2016/07/06 by Rolando.Caloca
