UE4纹理技术及相关命令

纹理（Texture）是材质中使用的图像。一个材质可能会有一张基础颜色的纹理贴图，一张高光纹理和一张法线贴图。除此以外，还有可能有自发光贴图以及粗造度贴图。另外，纹理也可以在材质之外直接使用，如绘制到HUD。

在大多数情况下，纹理在PhotoShop等外部软件里面创建，然后导入虚幻编辑器中。然而，有些纹理（如渲染纹理），则从场景中获取一些信息实时生成出来，并在其他地方使用。

 

虚幻引擎最大纹理mip数量为15，即最大渲染纹理size为16384。注：能支持多大size取决于图形硬件和驱动，目前PC和主机上顶级显卡最大可支持16384。

详见：UnrealEngine\Engine\Source\Runtime\RHI\Public\RHIDefinitions.h中的enum { MAX_TEXTURE_MIP_COUNT = 15 }

在UnrealEngine\Engine\Config\BaseDeviceProfiles.ini还可以进一步对不同Texture Group的纹理单独配置支持的最大纹理尺寸。

[/Script/Engine.TextureLODSettings]
TextureLODGroups=(Group=TEXTUREGROUP_World,MinLODSize=1,MaxLODSize=16384,LODBias=0,MinMagFilter=aniso,MipFilter=point,MipGenSettings=TMGS_SimpleAverage,NumStreamedMips=-1)

FTextureLODGroup中各字段说明：

字段 缺省值 解释
TextureGroup Group TEXTUREGROUP_World 纹理分组
int32 MinLODMipCount 0 最小Mip索引值 例如：为0时表示最小mip的级别为1
int32 MaxLODMipCount 12 最大Mip索引值  例如：为12时表示最大mip的级别为13
int32 LODBias 0

Texture Group(纹理分组)的LOD偏移

一个负值或正值，cook时确定要偏移的mip级别数量（会去掉高精度的mip，能有效减小包体）
int32 LODBias_Smaller -1 【低内存适配】Smaller档位内存(Android、IOS下为3-4GB)手机的LODBias
int32 LODBias_Smallest -1 【低内存适配】Smallest档位内存(Android为3GB、IOS下为2GB)手机的LODBias
ETextureSamplerFilter Filter   Mip采样类型 如：Point（最近点采样），linear（线性插值采样）、Anisotropic（各向异性采样）
int32 NumStreamedMips -1

NumStreamedMips为允许流送（Streaming）的mip数量。
如果纹理有10个mip，NumStreamedMips是2，则只允许流送输入或输出2个最高的mip（因此，该LOD组的纹理在内存中都有8-10个mip）。
将NumStreamedMips设置为0，意味着不流送任何mip，使用该LOD组的纹理始终完全加载。
将NumStreamedMips设置为-1(缺省值)，意味着允许流送输入或输出所有mip（注：实际上虚幻引擎对<=7的mip不进行流送，是常驻内存的）。
TextureMipGenSettings MipGenSettings TextureMipGenSettings::TMGS_SimpleAverage 自动Mip生成的算法 如：SimpleAverage、Sharpen0、...、Sharpen10、NoMipmaps、LeaveExistingMips、Blur1、Blur2、...、Blur5
int32 MinLODSize 1 渲染的最小mip的size，以像素为单位指定，为范围1到16384中的2的幂值
int32 MaxLODSize 4096 渲染的最大mip的size，以像素为单位指定，为范围1到16384中的2的幂值
int32 MaxLODSize_Smaller -1 【低内存适配】Smaller档位内存(Android、IOS下为3-4GB)手机的MaxLODSize
int32 MaxLODSize_Smallest -1 【低内存适配】Smallest档位内存(Android为3GB、IOS下为2GB)手机的MaxLODSize
FName MinMagFilter NAME_Aniso 缩小或放大某层mip纹理的采样类型 如：Point、Linear、Aniso
FName MipFilter NAME_Point 不同mip层进行混合采样的类型 如：Point、Linear
ETextureMipLoadOptions MipLoadOptions ETextureMipLoadOptions::AllMips mip加载选项  ①Default:使用LODGroup中的设置   ②AllMips：加载所有mips  ③OnlyFirstMip：仅加载最高级别的Mip

 

mip级别和size的关系如下：

Mip1 Mip2 Mip3 Mip4 Mip5 Mip6 Mip7 Mip8 Mip9 Mip10 Mip11 Mip12 Mip13 Mip14 Mip15
1x1 2x2 4x4 8x8 16x16 32x32 64x64 128x128 256x256 512x512 1024x1024 2048x2048 4096x4096 8192x8192 16384x16384

即：size=2^(级别-1)。另外，64x64的级别也可以用-1表示（内部转换时，当为-1时会将级别修改为7）

需要注意的是，虚幻引擎对<=7的mip不进行流送，是常驻内存的。

 

贴图（Texture2D）

注1：Maximum Texture Size为长边的最大纹理size，缺省值为0

注2：使用LeaveExistingMips，可以导入外部制作好的mipmap（只能是ARGB8888格式的dds）

注3：贴图Combined LOD Bias（最终的LOD偏移）最后由贴图属性中的LOD Bias、Num Cinematic Mip Levels（数值为1表示将贴图在游戏中的分辨率降低1个mip等级，而播放过场动画时不做降低）、Texture Group中的LOD Bias叠加得到。

         具体计算逻辑详见：UTextureLODSettings::CalculateLODBias函数

注4：烘焙贴图时，会将贴图中的Texture.LODBias +TextureGroup.LODBias个级别的高清mip层都删除掉（防止包体太大）。

        在过场动画时，使用的mip层级为剔除完Texture.LODBias +TextureGroup.LODBias后的剩余部分。而其他正常游戏时，使用的mip还要继续去掉NumCinematicMipLevels个高清mip层数。

注5：勾选Never Stream，所有mip将始终常驻内存

注6：更多Texture2D属性字段的说明，详见：纹理属性

 

MipMap

注1：勾上Mip Level，选择Level级别，会强制使用当前mip级别进行预览。

注2：不勾Mip Level，放大缩小贴图时，会根据MinMagFilter和MipFilter设定的过滤算法（各TextureGroup有指定自己的MinMagFilter和MipFilter），来显示贴图的像素颜色

mip级别和size的关系如下：

级别 Mip1 Mip2 Mip3 Mip4 Mip5 Mip6 Mip7 Mip8 Mip9 Mip10 Mip11 Mip12 Mip13
Level 12 11 10 9 8 7 6 5 4 3 2 1 0
size 1x1 2x2 4x4 8x8 16x16 32x32 64x64 128x128 256x256 512x512 1024x1024 2048x2048 4096x4096
颜色 白 白 白 白 白 白 紫 靛 蓝 绿 黄 橙 红

 

以下实验，修改完贴图的Filter之后，需重启编辑器来验证：

Filter为Nearest       注：MinMagFilter=point,MipFilter=point

或Filter为Bi-linear  注：MinMagFilter=linear,MipFilter=point

 

Filter为Tri-linear   注：MinMagFilter=linear,MipFilter=linear

 

Filter为Default(From Texture Group)   注：MinMagFilter=aniso,MipFilter=point  或MinMagFilter=aniso,MipFilter=linear

 

r.MipMapLODBias 0  // 不对mipmap精度进行偏移

r.MipMapLODBias 2  // 将mipmap精度降低2级

r.MipMapLODBias -2  // 将mipmap精度提高2级

 

贴图数组（TextureArray）

选择分辨率一样的贴图，然后右键选择“Create Texture Array”来创建贴图数组资源

 

创建出来的贴图数组资源如下：

 

立方体贴图（CubeMap）

立方体贴图（CubeMap）提供了一种进行环境映射的简单方法，通过这种方法，像天空、周围环境这样的远景可以映射到一个全景贴图上。

在底层，这些贴图存储为6张图片，映射到立方体的内表面上。更多信息详见：立方体贴图

 

3D贴图（TextureVolume）

3D贴图，又叫体积纹理，是一种特殊类型的资源，可以帮助在2D纹理中存储和使用3D体积信息。更多信息详见：体积纹理

 

LightMap和ShadowMap

当关卡xxxxx有LightMap（光照贴图）和ShadowMap（阴影贴图）时，会保存在xxxxx_BuiltData.uasset文件中。

在Levels面板中双击xxxxx关卡，可将xxxxx关卡设为当前关卡，然后切换到World Settings面板的Lightmass标签，就可以看到xxxxx关卡的LightMap和ShadowMap。双击这些LightMap和ShadowMap，即可打开。

 

Lightmass烘焙出的LightMap

 

Lightmass烘焙出的ShadowMap

 

注：计算颜色时，直接将LightMap、ShadowMap与BaseColor进行相乘

 

设备分档（DeviceProfile）

可通过菜单：Window -- Developer Tools -- Device Profiles来打开Device Profiles面板

注：左边面板每项前有一个小尖锥的图标，向下为Pin状态，表明该项会显示在右边list中，向右为UnPin状态，则表示该项不要显示在右边list中

 

载入Device Profiles面板上数据

按照如下顺序进行覆盖读取（后面覆盖前面的数据）：

① 引擎的UnrealEngine\Engine\Config\BaseDeviceProfiles.ini 

② 项目的Config\DefaultDeviceProfiles.ini（若存在的话）

③ 项目的Saved\Config\Windows\DeviceProfiles.ini （若存在的话）

 

保存Device Profiles面板上数据

点击右上角上的Save as Default按钮后，会将Device Profiles面板上的所有值保存到项目的Config\DefaultDeviceProfiles.ini    注：如果没有，则会创建一个

如果修改的数值，没有点击Save as Default按钮，则在关闭编辑器时，会将修改保存在项目的Saved\Config\Windows\DeviceProfiles.ini的临时文件中

 

继承关系

以Windows平台为例来进行说明

① 名称为Windows、WindowsNoEditor、WindowsServer、WindowsClient都属于Windows类型的平台

② WindowsNoEditor（windows客户端cook版本）、WindowsServer（windows ds cook版本）、WindowsClient会继承并覆写Windows的Profile数值    注：它们的Base Profile Name都为Windows

③ 修改Windows的Profile数值会影响所有的windows类型的程序（后续被覆写的数值除外）

 

以下为IOS相关的数据：

更多设备描述信息详见：设置设备描述、自定义Android的设备描述和可延展性

 

控制台变量（Console Variable）

r.TextureStreaming 0  // 关闭texture streaming。即使在纹理从来没有被用于渲染，所有纹理mip都将被完全加载到内存中。内存会暴增。

可进行如下设置来开启项目的TextureStreaming

这个设置会保存到DefaultEngine.ini中

[/Script/Engine.RendererSettings]

r.TextureStreaming=True

注1：可通过控制台变量r.TextureStreaming 0/1来动态修改关闭和开启Texture Streaming。关闭后，所有的mip都将被完全加载到内存中。

注2：开启了TextureStreaming之后，引擎会基于纹素大小（texel size）和物体的bounds来计算各个像素（pixel）最适合比例的纹理lod级别。若所需内存超过PoolSize大小，会取更小size的纹理lod级别。

 

r.Streaming.PoolSize  // 查看当前texture streaming内存池的大小  注1：该Pool包含UI纹理、NeverStream纹理、CubeMap和流送纹理。在某些平台上，这个池还可以保存非纹理资源，例如GPU粒子缓冲区和顶点缓冲区。 注2：该Pool为Texture显存的上限。

r.Streaming.PoolSize 0  // 设置texture streaming内存池的大小为不受限制

r.Streaming.PoolSize 100  // 设置texture streaming内存池的大小为100MB   注：也可通过stat streaming来看到其当前大小

Required Pool：纹理流送器需要根据其指标加载的mip数据量。Required Pool超过r.Streaming.PoolSize时，会进行一些妥协，部分纹理将不会以其所要求的分辨率加载。

Visible Mips：可见纹理mip当前占用的内存。这并不包含Forced Mips。

Hidden Mips：非可见纹理mip当前占用的内存。这并不包含Forced Mips。为防止首次显示纹理时出现低精度纹理，流送器会提前预流送纹理，但通常会比所需要的少一个 mip（详见 r.Streaming.HiddenPrimitiveScale）。

Forced Mips：强制流入纹理当前占据的内存。纹理通常通过游戏性机制在一小段时间内强制流入。这并不包含NonStreaming Mips。

Cached Mips：不再需要的纹理mip所占据的缓存。当纹理流送器内存不够时，会被释放用来流入所需的Mips。

Wanted Mips：实际流入的所需池大小。达到 100% 后，流送器将停止发送 IO 请求加载新 mip。Wanted Mips 等于 Visible Mips + Hidden Mips + Forced Mips + UnknownRef Mips

Safety Pool：Engine配置文件中，[TextureStreaming]标签下的MemoryMargin配置的数值。

Temporary Pool：调整纹理大小时流送器可用的额外内存量，由r.Streaming.MaxTempMemoryAllowed 控制。

Streaming Pool：为r.Streaming.PoolSize配置的数值。流送器通常会将所有可用内存用于流送新 mip，或将之前流送的 mip 尽可能久地保存在内存中。

                             Streaming当前实际占用的内存为：约等于Visible Mips + Hidden Mips + Force Mips + UnknownRef Mips + Cached Mips。

NonStreaming Mips：常驻Mips占用的内存。

Texture使用的内存约等于 Safety Pool(5 MB) + Temporary Pool(50 MB) + Visible Mips(0.15 MB) + Hidden Mips(0.0 MB) + Force Mips(0.0 MB) + UnknownRef Mips(42.68 MB) + Cached Mips(0.0 MB) + NonStreaming Mips(66.4 MB) = 164.23 MB

更多stat streaming说明请参考：报告纹理流送指标

 

 

当r.Streaming.PoolSize很小时，会在左上角提示：TEXTURE STREAMING POOL OVER XXX MiB BUDGET

场景中显示的纹理也会变得很糊，效果不好

r.Streaming.PoolSizeForMeshes  1 // Mesh使用独立的PoolSize，为-1（缺省值）时Mesh和Texture共用Pool  单位MB

r.Streaming.FramesForFullUpdate  1000  // 每次完整更新的帧数间隔设为100帧。缺省值为5帧。每次更新都会重新计算每个纹理所需的分辨率，并生成mip加载或卸载请求。较高的值会降低纹理流送器CPU使用率，而较低的值则会提高其反应能力。

r.Streaming.MaxTempMemoryAllowed 30  // 设置更新纹理的临时内存量为30MB，缺省为20MB。设置太大会浪费内存，设置过小则会让纹理流送器的吞吐量低。

r.Streaming.HLODStrategy 0 // 将HLOD的Stream策略为0  注：0 : 允许流送所有mip。  1 : 仅流送最后一个mip，始终加载其他mip。  2 : 不流送任何mip，始终加载所有mip。

r.Streaming.DropMips 2  // 丢掉Cache Mips和Hidden Mips  注：0 : 不丢掉任何mip。 1 : 丢掉缓存的mip。 2 : 丢掉缓存和隐藏的mip。

r.Streaming.HiddenPrimitiveScale 0.8  // 物体不可见（即其边界框被遮挡）时，提前将最大分辨率的0.8倍对应分辨率的mip载入，防止首次显示纹理时出现低精度纹理。

r.Streaming.UsePerTextureBias  1  // 设置为1表示每个贴图使用自己的Bias，不使用全局MipBias

r.Streaming.MipBias 3   // 设置全局的MipBias为3，所有贴图、静态模型都会从最高精度向下偏移3个层级的mip   注1：r.Streaming.UsePerTextureBias需设置为0，该命令才会生效   注2：不影响地形贴图的Bias。不限制HLOD贴图的最大分辨率。对LightMap和ShadowMap仅限制最大分辨率

r.Streaming.TextureMipBias 2 // 设置全局的MipBias为2，所有贴图都会从最高精度向下偏移2个层级的mip  注：uam自己扩展的命令

r.UITextureLODBias 1  // 设置所有UI贴图的MipBias为1   注1：UI贴图需要包含mipmap数据   注2：对已经加载了UI贴图不生效，对后续加载的UI贴图生效

更多控制台变量详见：纹理流送配置

 

一些全局变量

/** True if the RHI supports texture streaming */
extern RHI_API bool GRHISupportsTextureStreaming;
/** Amount of memory allocated by textures. In kilobytes. */
extern RHI_API volatile int32 GCurrentTextureMemorySize;
/** Amount of memory allocated by rendertargets. In kilobytes. */
extern RHI_API volatile int32 GCurrentRendertargetMemorySize;
/** Current texture streaming pool size, in bytes. 0 means unlimited. */
extern RHI_API int64 GTexturePoolSize;

 

对于场景中的StaticMesh对象，可勾选Force Mip Streaming，让该物件所有的MipMap贴图常驻内存

注：设置StaticMeshActor的Streaming Distance Multiplier（流送距离乘数）的值，会影响StaticMeshActor的Primitive Distance的数值。

 

构建纹理流送（Build Texture Streaming）

执行Build Texture Streaming，会将以下信息保存到关卡的umap及BuiltData.uasset文件中

① Primitive的bound

② StaticMesh的纹理坐标大小

③ 对每个纹理采样的纹理坐标的scale

利用这些信息，引擎可以更准确地按照距离选择Texture对应的mip层级    注：如果没有build，引擎会使用保守式启发的算法来选择

 

画质分档（Scalability）

将Quality分为Low(0)、Medium(1)、High(2)、Epic(3)、Cinematic(4)，共五档。

CurrQualityLevels.SetFromSingleQualityLevel(LevelNum); // LevelNum : 0(Low),  1(Medium),  2(High),  3(Epic),  4(Cinematic)
Scalability::SetQualityLevels(CurrQualityLevels, true);

 

FQualityLevels结构体详见：

/** UnrealEngine\Engine\Source\Runtime\Engine\Public\Scalability.h */
namespace Scalability
{ 
    // ... ...

    /**
     * Structure for holding the state of the engine scalability groups
     * Actual engine state you can get though GetQualityLevels().
    **/
    struct ENGINE_API FQualityLevels

};

 

使用控制台命令来设置Quality

SCALABILITY auto  // 自动执行Scalability::BenchmarkQualityLevels()来测试cpu和gpu性能，来决定给各个子项分别设置什么档位，并将信息保存ini配置文件中

SCALABILITY reapply  // 获取当前Scalability::GetQualityLevels()来设置一遍

SCALABILITY cine  // 设置到最高Cinematic档位，并将信息保存ini配置文件中

SCALABILITY N  // 当N为1即设置到Medium档位，并将信息保存ini配置文件中
