Màscara

Shadow Catcher

Enables the object to only receive shadow rays. It is to be noted that, shadow catcher objects will interact with other CG objects via indirect light interaction. This simplifies compositing CGI elements into real-world footage.

Nota

The Shadow Catcher outputs different results depending on if the Shadow Catcher pass is enabled in Render Layer settings. With the Shadow Catcher pass enabled, all indirect light interactions are captured. With it disabled, a simple approximation is used instead. The simple approximation is used in viewport rendering.

Example of the shadow catcher. Note how the material of the plane can still be viewed in the spheres.

Ray Visibility

Objects can be set to be invisible to particular ray types. This can be used, for example, to make an emitting mesh invisible to camera rays. For instanced objects, visibility is inherited; if the parent object is hidden for some ray types, the children will be hidden for these too.

Pel que fa al rendiment, l’ús d’aquestes opcions és més eficient que l’ús d’una configuració de node aspector que aconsegueixi el mateix efecte. Els objectes que són invisibles a un determinat raig ja s’ometran en la travessa de rajos, la qual cosa conduirà a menys irradiacions i execucions d’aspectors.

Càmera

Makes the object visible to the Camera; this includes the viewport’s perspective in viewport rendering.

Difusiva

Makes the object visible in diffuse rays.

Setinat

Makes the object visible in glossy rays.

Transmissió

Makes the object visible in transmission rays.

Volume Scatter

Makes the object visible in volumetric scatter rays.

Ombra

Enables the object to cast shadows.

Culling

In order to activate these options the respectively camera cull options have to be enabled in the scene simplify panel.

Use Camera Cull

Ignore and this way make objects invisible to rays outside of the camera frustum.

Use Distance Cull

Will cull any objects further from the camera than a given distance. When used in combination with camera frustum culling, this can be used to avoid culling nearby objects that are outside the camera frustum, but still visible in reflections. It is also useful to cull small objects far from the camera.

Propietats ‣ Propietats d’objecte ‣ Borra de moviment

Each object has its own motion blur settings along with the Scene Level Motion Blur. These settings can be found in the Object Properties tab of the Properties.

Passes

Controls accuracy of deformation motion blur, more steps uses more memory. The actual number of time steps is \(2^{steps -1}\).

Deformació

Enables motion blur for deformed meshes such as animated characters, including hair.

Avís

An object modifier setup that changes mesh topology over time can not render deformation motion blur correctly. Deformation blur should be disabled for such objects. Common examples of this are animated Booleans, Deformation before Edge Split, Remesh, Skin or Decimate modifiers.

Shadow Terminator

Geometry Offset

Offset rays from the surface to reduce shadow terminator artifacts on low-poly geometry. Higher values affect more triangles, a value of one affecting all triangles and zero having no affect. The default value only affects triangles at grazing angles to light and should eliminate most artifacts.

Unlike the Shading Offset, this option has little affect on the lighting making it the preferable method to handle shadow terminator artifacts.

Shading Offset

Pushes the shadow terminator (the line that divides the light and dark) towards the light to hide artifacts on low-poly geometry such as the ones below:

Shadow Terminator Artifacts.

Result of using an offset of 0.15.

Nota

This property artificially alters the scene’s lighting and is not energy conserving and consequently not physically accurate (see Geometry Offset instead).

Fast GI Approximation

AO Distance

Override for the world’s AO Distance, if the value is zero the world’s distance is used.

Càustica

Marca els objectes com a projectors o receptors de càustica. Això s’utilitza conjuntament amb un Llum o bé un Aspector de del món amb Càustica d’ombra habilitada per a accelerar selectivament la revelat de càustica dels objectes a la vostra escena.

Nota

La tècnica de revelat utilitzada per a accelerar el revelat de càustica es basa en MNEE. Aquesta tècnica té una sèrie de limitacions i s’implementa en Cycles:

• Only refractive caustics in the shadows of objects work. Caustics from reflections or caustics that fall outside shadows are not rendered with this technique.

• MNEE Caustics are an approximation of caustics and will produce physically inaccurate results in many situations. Examples include incorrect brightnesses and the incorrect representation of caustics caused by rough or curved surfaces.

• In complex materials with multiple refractive BSDFs, MNEE will only generate caustics for one of the BSDFs.

• Filter Glossy settings are ignored when using MNEE for refractive caustics.

• MNEE Caustic rays can pass through up to 6 Caustic Caster surfaces between a Caustic Receiver and a Shadow Caustic light before the ray is terminated and caustics are ignored.

• Els nodes Oclusió ambiental i Bisell no produiran un resultat vàlid en objectes que són projectors o receptors de Càustica mentre l’escena contingui un projector actiu de Càustica, receptor actiu de Càustica i Llum càustica d’ombra asp.

• MNEE Caustics only work if the caustic caster has smooth normals.

• Volumetric materials are not considered when calculating MNEE caustics.

• Bump and normal maps are ignored when calculating caustics.

Cast Shadow Caustics

Mark an object as a caustic caster.

Receive Shadow Caustics

Mark an object as a caustic receiver.

Limit light influence to specified objects, with Light Linking.

Receiver Collection

Collection of objects that will receive light emitted from the object.

Shadow Linking

Limit shadows to specified objects, with Light Linking.
