Passos
Reference
- Panel:
Passos podem ser usados para dividir imagens renderizadas em cores, luz direta e indireta para editá-las individualmente, e também extrair informações como profundidade ou normais.
Dados
Cíclico(a)
- Include
- Combinado
A combinação final dos passos de renderização com tudo incluído.
- Z
Distance to any visible surfaces.
Nota
The Z pass only uses one sample. When depth values need to be blended in case of motion blur or Depth of Field, use the mist pass.
- Névoa
Distance to visible surfaces, mapped to the 0.0 - 1.0 range. When enabled, settings are in World tab. This pass can be used in compositing to fade out objects that are farther away.
- Posição
World position of objects in the scene.
- Normal
Normais da superfície usadas para sombreamento.
- Vector
Motion vectors for the Vector Blur node. The four components consist of 2D vectors giving the motion towards the next and previous frame position in pixel space.
- UV
Mapped UV coordinates, used to represent where on a mesh a texture gets mapped too. This is represented through the red and green channels of the image. The blue channel is encoded with a constant value of 1 but does not hold any information.
- Denoising Data
Includes Denoising Albedo, Denoising Normal, and a render pass of the original combined pass before denoising.
Nota
The Z, Position, Object Index, and Material Index passes are not anti-aliased.
- Indexes
- Índice de objeto
Creates a mask of the object that can be later read by the ID Mask Node in the Compositor.
- Material Index
Creates a mask of the material that can be later read by the ID Mask Node in the Compositor.
- Debug
- Sample Count
Number of samples/camera rays per pixel, to analyze adaptive sampling.
- Ajuste de alfa
Passos Z, Índice, normal, UV e vetor são afetados apenas pelas superfícies com transparência alfa iguais ou maiores que o valor desse ajuste. Com um valor de 0.0 a primeira superfície atingida irá sempre escrever para esses passos, independente da transparência. Com valores maiores as superfícies que são mais transparentes podem ser evitadas até que uma superfície opaca é encontrada.

- Include
- Combinado
A combinação final dos passos de renderização com tudo incluído.
- Z
Distance to any visible surfaces.
- Névoa
Distance to visible surfaces, mapped to the 0.0 - 1.0 range.
- Normal
Normais da superfície usadas para sombreamento.
Leve
Cíclico(a)
- Difusa
- Direct
Direct lighting from diffuse and subsurface BSDFs. We define direct lighting as coming from lights, emitting surfaces, the background, or ambient occlusion after a single reflection or transmission off a surface. BSDF color is not included in this pass.
- Indirect
Indirect lighting from diffuse and subsurface BSDFs. We define indirect lighting as coming from lights, emitting surfaces or the background after more than one reflection or transmission off a surface. BSDF color is not included in this pass.
- Color
Color weights of diffuse and subsurface BSDFs. These weights are the color input socket for BSDF nodes, modified by any Mix and Add Shader nodes.
- Polimento
- Direct, Indirect, Color
Mesmo que acima, mas para BSDFs de polimento.
- Transmissão
- Direct, Indirect, Color
Mesmo que acima, mas para BSDFs de transmissão.
- Volume
- Direct, Indirect
Same as above, but for volumetric BSDFs.
- Other
- Emissão
Emissão de superfícies vistas diretamente.
- Ambiente
Emissão do plano de fundo visível diretamente. Quando o filme é definido para transparente, isso pode ser usado para pegar a cor do ambiente e compor de volta.
- Oclusão ambiente
Oclusão ambiente de superfícies visíveis diretamente. Cor BDSF ou fator OA não são incluídos; isto é, fornece um valor “normalizado” entre 0 e 1.
- Capturador de sombras
Extra indirect light information collected by objects with the Shadow Catcher option enabled. Multiply this pass with existing footage using the Misturar in the Compositor to add the indirect lighting information to the footage.
Nota
Transparent BSDFs are given special treatment. A fully transparent surface is treated as if there is no surface there at all; a partially transparent surface is treated as if only part of the light rays can pass through. This means it is not included in the Transmission passes; for that a glass BSDF with index of refraction 1.0 can be used.
Eevee
- Difusa
- Leve
Direct lighting from diffuse BSDFs. We define lighting as coming from lights, the background, or ambient occlusion off a surface. BSDF color is not included in this pass.
- Color
Peso das cores de BSDFs difusos. Esses pesos são as entradas dos soquetes de cor para os nós BSDF, modificados por quaisquer nós sombreadores Misturar e Adicionar.
- Especular
- Light, Color
Same as above, but for specular BSDFs.
- Volume
- Leve
The scattering pass from volume objects or world.
- Other
- Emissão
Emissão de superfícies vistas diretamente.
- Ambiente
Emissão do plano de fundo visível diretamente. Quando o filme é definido para transparente, isso pode ser usado para pegar a cor do ambiente e compor de volta.
- Shadow
Shadows from light objects. Mostly useful for compositing objects with shadow into existing footage.
- Oclusão ambiente
Oclusão ambiente de superfícies visíveis diretamente. Cor BDSF ou fator OA não são incluídos; isto é, fornece um valor “normalizado” entre 0 e 1.
Efeitos
Eevee only
- Bloom
The influence of the Bloom effect.
- Transparency
Contain Alpha Blended surfaces, so they can be adjusted in the compositor and later mixed with opaque passes.
This pass only supports monochromatic opacity. Colored opacity will show differently than in combined pass.
Cryptomatte
Cryptomatte is a standard to efficiently create mattes for compositing. Cycles outputs the required render passes, which can then be used in the Blender Compositor or another compositor with Cryptomatte support to create masks for specified objects.
Unlike the Material and Object Index passes, the objects to isolate are selected in compositing. The mattes will be anti-aliased and take into account effects like motion blur and transparency.
- Objeto
Render cryptomatte object pass, for isolating objects in compositing.
- Material
Render cryptomatte material pass, for isolating materials in compositing.
- Asset
Render cryptomatte asset pass, for isolating groups of objects with the same parent in compositing.
- Levels
Sets how many unique objects can be distinguished per pixel.
Typical Workflow
Enable Cryptomatte Object render pass in the Passes panel, and render.
In the compositing nodes, create a Cryptomatte node and link the Render Layer matching Image and Cryptomatte passes to it.
Attach a Viewer node to the Pick output of the Cryptomatte node.
Use the Cryptomatte Add/Remove button to sample objects in the Pick Viewer node.
Use the Matte output of the Cryptomatte node to get the alpha mask.

Shader AOV
Shader AOVs (Arbitrary Output Variables) provide custom render passes for any shader node components. As an artist this can be a good way to fix or tweak fine details of a scene in post-processing. To use Shader AOVs create the pass in the Shader AOV panel then reference this pass with the AOV Output shading node. Shader AOVs can be added or removed in the Shader AOV panel. In this panel is a list of all AOV passes; each AOV in the list consists of a Name and Data Type.
- Active AOV Index
The name of the render pass; this is the Name that is referenced in the AOV Output node. Any names can be used for these passes, as long as they do not conflict with built-in passes that are enabled.
- Data Type
Shader AOVs can either express a Color or a Value output. The Color type as the name suggest can be used for a color but also for normals. A Value type can be used for any single numerical value.
Light Groups
Cycles only
Light Groups provide render passes that only contains information from the lights within that group. Light Groups can be used to easily tweak the lighting color and intensity of specific lights without having to re-render the scene.
- Active Light Group Index
The name of the render pass. This is the name that is used when adding World Shaders, Lights and Objects to Light Groups.
Lightgroup Sync
These operators are available in the menu to the right of the Light Group list.
- Add Used Lightgroups
Adds all Light Groups to the View Layer that have been created elsewhere and have lights assigned to them.
- Remove Unused Lightgroups
Deletes all Light Groups that do not have any lights assigned to them.
Combinando
Cíclico(a)
Todos esses passo de iluminação podem ser combinados para produzir a imagem final como segue:
Eevee
The passes can be combined to produce the final image as follows:
Known Limitations
Alpha blended materials are not rendered in render passes except the combined pass. Use the Alpha Clip or Alpha Hashed as Blending Mode to render transparent materials in render passes.
Depth of field is not rendered in render passes except the combined pass. It is possible to add the depth of field back in the Compositor using the Defocus node.
Eevee render passes exclude parts of the BSDF equation. Shader to RGB is not supported as it needs the full BSDF equation.
