Existem várias outras propriedades de general visibility.

Mask
Capturador de sombras

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.

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.

In terms of performance, using these options is more efficient that using a shader node setup that achieves the same effect. Objects invisible to a certain ray will be skipped in ray traversal already, leading to fewer ray casts and shader executions.

Câmera

Torna o objeto visível para os raios da câmera.

Difusa

Torna o objeto visível para os raios de cores difusas.

Polimento

Torna os objetos visíveis para os raios de polimento de objetos.

Transmissão

Torna os raios visíveis para raios de transmissão.

Espalhamento de volume

Torna os raios visíveis para raios de transmissão.

Shadow

Permite que este objeto projete sombras.

Culling

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

Usar abatimento pela câmera

Ignora e desta maneira torna os objetos invisíveis aos raios fora do tronco de raios paralelos da câmera (frustrum).

Usar a distância para abatimento

Irá abater quaisquer objetos que estiverem mais longes do que uma determinada distância da câmera. Quando usado em combinação com o abatimento de projeção da câmera (frustrum), isto pode ser usado para evitar que haja abatimento nos objetos que estão fora da visibilidade da projeção da câmera, mas ainda visíveis nas reflexões. Isto também é útil para abater pequenos objetos que estão distantes da câmera.

Desfoque de movimento

Reference

Panel

Properties ‣ Object Properties ‣ Motion Blur

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.

Passos

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

Deformação

Habilita o desfoque de movimento para as malhas deformadas como as dos personagens animados, incluindo cabelos.

Aviso

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.

Shading

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.

../../../_images/render_cycles_object-settings_object-data_shading-terminator2.jpg

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.

Caustics

Mark objects as caustic casters or receivers. This is used in conjunction with a Light or World Shader with Shadow Caustics enabled to selectively speed up caustic rendering of objects in your scene.

Nota

The rendering technique used to speed up the rendering of caustics is based on MNEE. There are a number of limitations with this technique and it’s implementation in 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 product 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 Reciever and a Shadow Caustic light before the ray is terminated and caustics are ignored.

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

  • Volumetric materials can not considered when calculating MNEE caustics.

  • Bump and normal maps are ignored when calculating caustics.

  • The Metal GPU rendering backend is not supported.

Cast Shadow Caustics

Mark an object as a caustic caster.

Receive Shadow Caustics

Mark an object as a caustic receiver.

Select the Light Group to add the current Object or Light too.

Add Light Group

If the name input into the Light Group field does not align with an existing Light Group, then pressing this button will create a Light Group with that name and assign the selected Object or Light to it.
