Renderer

Allow uniform expressions to be cached.

No description provided.

If true, use enable depth bounds test when rendering defered lights.

Enables mesh shaders to support a global clip plane, needed for planar reflections, which adds about 15% BasePass GPU cost on PS4.

Creates an HDR compatible swap-chain and enables HDR display output.0: Disabled (default) 1: Allow HDR, if supported by the platform and display

Allow Landscape Shadows

Enable experimental multi-GPU support in editor

If zero, occlusion queries will not be used to cull primitives.

When 0, will prevent point light cube map shadows from being used and the light will be unshadowed.

If zero, precomputed visibility will not be used to cull primitives.

If true, we allow simple (ie particle) lights

Whether to allow any static lighting to be generated and used, like lightmaps and shadowmaps. Games that only use dynamic lighting should set this to 0 to save some static lighting overhead.

Enables sub primitive queries, currently only used by hierarchical instanced static meshes. 1: Enable, 0 Disabled. When disabled, one query is used for the entire proxy.

Enable UTexture2DArray assets

Performance tweak. If > 0, then use a sphere cull before and in addition to a box for frustum culling.

Defines which level of EAsyncComputeBudget to use for balancing AsyncCompute work against Gfx work. Only matters if the compute version of SSAO is active (requires CS support, enabled by cvar, single pass, no normals) This is a low level developer tweak to get best performance on hardware that supports AsyncCompute. 0: least AsyncCompute 1: .. (default) 2: .. 3: .. 4: most AsyncCompute

If SSAO should use ComputeShader (not available on all platforms) or PixelShader. The [Async] Compute Shader version is WIP, not optimized, requires hardware support (not mobile/DX10/OpenGL3), does not use normals which allows it to run right after EarlyZPass (better performance when used with AyncCompute) AyncCompute is currently only functional on PS4. 0: PixelShader (default) 1: (WIP) Use ComputeShader if possible, otherwise fall back to \'0\' 2: (WIP) Use AsyncCompute if efficient, otherwise fall back to \'1\' 3: (WIP) Use AsyncCompute if possible, otherwise fall back to \'1\'

Whether to smooth SSAO output when TAA is disabled

Choose the denoising algorithm. 0: Disabled; 1: Forces the default denoiser of the renderer; 2: GScreenSpaceDenoiser witch may be overriden by a third party plugin (default).

Multiplication factor applied on the kernel sample offset (default = 7).

Number of samples to use for history post filter (default = 16).

Spread factor of the preconvolution passes.

Number of pre-convolution passes (default = 1).

Maximum number of samples for the reconstruction pass (default = 16).

Accumulates the samples over multiple frames.

Whether to use depth bounds test to cull distant pixels during AO pass. This option is only valid when pixel shader path is used (r.AmbientOcclusion.Compute=0), without upsampling.

Allows to scale the ambient occlusion fade radius (SSAO). 0.01:smallest .. 1.0:normal (default), <1:smaller, >1:larger

Select between SSAO methods 0: SSAO (default) 1: GTAO

Defines how many mip levels are using during the ambient occlusion calculation. This is useful when tweaking the algorithm. <0: decide based on the quality setting in the postprocess settings/volume and r.AmbientOcclusionMaxQuality (default) 0: none (disable AmbientOcclusion) 1: one 2: two (costs extra performance, soft addition) 3: three (larger radius cost less but can flicker)

Defines the max clamping value from the post process volume\'s quality level for ScreenSpace Ambient Occlusion 100: don\'t override quality level from the post process volume (default) 0..99: clamp down quality level from the post process volume to the maximum set by this cvar -100..0: Enforces a different quality (the absolute value) even if the postprocessvolume asks for a lower quality.

Controls mipmap level according to the SSAO step id 0: always look into the HZB mipmap level 0 (memory cache trashing) 0.5: sample count depends on post process settings (default) 1: Go into higher mipmap level (quality loss)

Allows to scale the ambient occlusion radius (SSAO). 0:off, 1.0:normal, <1:smaller, >1:larger

Allows to override the Ambient Occlusion Static Fraction (see post process volume). Fractions are between 0 and 1. <0: use default setting (default -1) 0: no effect on static lighting, 0 is free meaning no extra rendering pass 1: AO affects the stat lighting

Disable support for ASTC Texture compression if OpenGL driver supports it. (Android Only) 0 = ASTC texture compression will be used if driver supports it [default] 1 = ASTC texture compression will not be used.

Disable support for OpenGLES 3.1 API. (Android Only) 0 = OpenGLES 3.1 API will be used (providing device and project supports it) [default] 1 = OpenGLES 3.1 will be disabled, Vulkan will be used.

Disable support for vulkan API. (Android Only) 0 = Vulkan SM5 API will be used (providing device and project supports it) [default] 1 = Vulkan SM5 will be disabled, Vulkan or OpenGL fall back will be used.

Disable support for vulkan API. (Android Only) 0 = vulkan API will be used (providing device and project supports it) [default] 1 = vulkan will be disabled, opengl fall back will be used.

Override external texture support for OpenGLES API. (Android Only) 0 = normal detection used [default] 1 = disable external texture support 2 = force ImageExternal100 (version #100 with GL_OES_EGL_image_external) 3 = force ImageExternal300 (version #300 with GL_OES_EGL_image_external) 4 = force ImageExternalESSL300 (version #300 with GL_OES_EGL_image_external_essl3)

Sets whether or not to allow threaded rendering for a particular Android device profile. 0 = Allow threaded rendering [default] 1 = Disable creation of render thread on startup

Sets whether or not to allow threaded rendering for a particular Android device profile on the initial load. 0 = Allow threaded rendering on the initial load [default] 1 = Disable threaded rendering on the initial load

Whether anisotropic BRDF is used for material with anisotropy.

Engine default (project setting) for AntiAliasingMethod is (postprocess volume/camera/game setting still can override) 0: off (no anti-aliasing) 1: Fast Approximate Anti-Aliasing (FXAA) 2: Temporal Anti-Aliasing (TAA) 3: Multisample Anti-Aliasing (MSAA, Only available on the desktop forward renderer) 4: Temporal Super-Resolution (TSR, Default)

Whether to apply DFAO as indirect shadowing even to static indirect sources (lightmaps + stationary skylight + reflection captures)

Whether to asynchronously build distance field volume data from meshes.

Determines how much memory should be allocated in distance field object culling data structures. Too much = memory waste, too little = flickering due to buffer overflow.

No description provided.

Whether to use the compute shader version of the distance field normal computation.

Exponent used to derive each clipmap\'s size, together with r.AOInnerGlobalDFClipmapDistance.

Resolution of the global distance field. Higher values increase fidelity but also increase memory and composition cost.

World space distance along a cone trace to switch to using the global distance field instead of the object distance fields. This has to be large enough to hide the low res nature of the global distance field, but smaller values result in faster cone tracing.

Whether to use a global distance field to optimize occlusion cone traces. The global distance field is created by compositing object distance fields into clipmaps as the viewer moves through the level.

Average expected number of objects per page, used to preallocate memory for the cull grid.

No description provided.

Whether to update the Global SDF for fast camera movement - lower quality, faster updates so lighting can keep up with the camera.

Meshes with a smaller world space radius than this are culled from the global SDF.

Meshes with a smaller radius than this number of voxels are culled from the global SDF.

Resolution divider for the mip map of a distance field clipmap.

Num clipmaps in the global distance field. Setting this to anything other than 4 is currently only supported by Lumen.

Expected sparse global distacne field occupancy for the page atlas allocation. 0.25 means 25% - filled and 75% - empty.
