17:52\n\n## 决定渲染顺序的因素\n\n![Alt text](assets/1617976734905.png)\n\n### Camera Depth\n\n按照Camera的Depth值从低到高的顺序，逐个Camera进行渲染。\n\n![Alt text](assets/1617962792081.png)\n\n每个Camera绘制的内容可以在CullingMask当中设置——设置绘制哪些Layers的物体\n\n![Alt text](assets/1617962839947.png)\n\n物体的Layer可以在Inspector面板进行设置。\n\n![Alt text](assets/1617962903268.png)\n\n### Opaque-Skybox-Transparent\n\nQueue<=2500 - Opaque\nQueue>=2501 - Transparent\n\n### Sorting Layers + Order in Layer\n\n可在Project Settings->Tags and Layers->SortingLayers中添加Layer。\n\n![Alt text](assets/1617975393846.png)\n\n在ParticleSystem、Sprite等Unity动态生成网格的Component中设置Sorting Layer与Order in Layer，来决定物体绘制的顺序，绘制时按从小到大排序。\n\n![Alt text](assets/1617976086216.png)\n\n![Alt text](assets/1617976104615.png)\n\n### RenderQueue\n\nRenderQueure是Material的一个属性。\n按照渲染队列，从低到高绘制。\n\nBackground (1000) - rendered before any others. You’d typically use this for things that really need to be in the background.\n\nGeometry (default) (2000) - this is used for most objects. Opaque geometry uses this queue.\n\nAlphaTest (2450) - alpha tested geometry uses this queue. It’s a separate queue from Geometry one since it’s more efficient to render alpha-tested objects after all solid ones are drawn.\n\nTransparent (3000) - this render queue is rendered after Geometry and AlphaTest, in back-to-front order. Anything alpha-blended (i.e. shaders that don’t write to depth buffer) should go here (glass, particle effects).\n\nOverlay (4000) - this render queue is meant for overlay effects. Anything rendered last should go here (e.g. lens flares, UI).\n\n### Sorting Fudge\n\nParticle System组件还有一个属性：Sorting Fudge，在其他值都相同时，这个值会影响绘制的先后顺序，值比较高的先绘制。\n\n![Alt text](assets/1617976537790.png)\n\n### 深度排序\n\n按照 **包围盒** 中心点的深度进行排序\n\n * 不透明物体 - 由近到远（从前向后）\n\n * 透明物体 - 由远到近（从后向前）\n\n## 实践建议\n\n### 明确分层\n\n例如UI上的半透明（特效、面片）始终在3D场景之上，则一般分多个相机来绘制。\n大片填充率的物件，例如地形，天空等，一般为提高深度命中，都会选择在延后批次绘制。\nDraw character before the terrain.\n\n## Ref\n\n\n" }
