Node type customization using name suffixes

Muitas vezes, ao editar uma cena, há tarefas comuns que precisam ser feitas após a exportação:

• Adicionando detecção de colisão a objetos.

• Definindo objetos como malhas de navegação.

• Deleting nodes that are not used in the game engine (like specific lights used for modeling).

To simplify this workflow, Godot offers several suffixes that can be added to the names of the objects in your 3D modeling software. When imported, Godot will detect suffixes in object names and will perform actions automatically.

Aviso

All the suffixes described below can be used with -, $, and _ and are case-insensitive.

Opting out

If you do not want Godot to perform any of the actions described below, you can set the nodes/use_node_type_suffixes import option to false. This will disable all node type suffixes, which keeps nodes the same type as the original file indicated. However, the -noimp suffix will still be respected, as well as non-node suffixes like -vcol or -loop.

Alternatively, you can completely opt out of all name suffixes by setting the nodes/use_name_suffixes import option to false. This will completely stop the general scene import code from looking at name suffixes. However, the format-specific import code may still look at name suffixes, such as the glTF importer checking for the -loop suffix.

Disabling these options makes editor-imported files more similar to the original files, and more similar to importing files at runtime. For an import workflow that works at runtime, gives more predictable results, and only has explicitly defined behavior, consider setting these options to false and using GLTFDocumentExtension instead.

Remove nodes and animations (-noimp)

Nodes and animations that have the -noimp suffix will be removed at import time no matter what their type is. They will not appear in the imported scene.

This is equivalent to enabling Skip Import for a node in the Advanced Import Settings dialog.

Criar colisões (-col, -convcol, -colionly, -convcolonly)

A opção -col funcionará apenas para objetos Mesh. Se for detectado, um nó de colisão estática filho será adicionado, usando a mesma geometria da malha. Isto criará uma forma de colisão de malha de triângulo, que é uma opção lenta, mas precisa para a detecção de colisão. Esta opção é normalmente o que você quer para geometria de fase (mas veja também -colonly abaixo).

The option -convcol will create a ConvexPolygonShape3D instead of a ConcavePolygonShape3D. Unlike triangle meshes which can be concave, a convex shape can only accurately represent a shape that doesn't have any concave angles (a pyramid is convex, but a hollow box is concave). Due to this, convex collision shapes are generally not suited for level geometry. When representing simple enough meshes, convex collision shapes can result in better performance compared to a triangle collision shape. This option is ideal for simple or dynamic objects that require mostly-accurate collision detection.

No entanto, em ambos os casos, a geometria visual é muito complexa ou muito irregular para colisões. Isto pode criar falhas físicas e retardar o motor desnecessariamente.

To solve this, the -colonly modifier exists. It will remove the mesh upon importing and will create a StaticBody3D collision instead. This helps the visual mesh and actual collision to be separated.

The option -convcolonly works in a similar way, but will create a ConvexPolygonShape3D instead using convex decomposition.

With Collada files, the option -colonly can also be used with Blender's empty objects. On import, it will create a StaticBody3D with a collision node as a child. The collision node will have one of a number of predefined shapes, depending on Blender's empty draw type:

Choosing a draw type for an Empty on creation in Blender

• Single arrow will create a SeparationRayShape3D.

• Cube will create a BoxShape3D.

• Image will create a WorldBoundaryShape3D.

• Sphere (and the others not listed) will create a SphereShape3D.

Quando possível, tente usar algumas formas de colisão primitivas ao invés de malhas triangulares ou formas convexas. As formas primitivas costumam ter o melhor desempenho e confiabilidade.

Nota

For better visibility on Blender's editor, you can set the "X-Ray" option on collision empties and set some distinct color for them by changing Edit > Preferences > Themes > 3D Viewport > Empty.

If using Blender 2.79 or older, follow these steps instead: User Preferences > Themes > 3D View > Empty.

Create Occluder (-occ, -occonly)

If a mesh is imported with the -occ suffix an Occluder3D node will be created based on the geometry of the mesh, it does not replace the mesh. A mesh node with the -occonly suffix will be converted to an Occluder3D on import.

Criar navegação (-navmesh)

Um nó de malha com o sufixo -navmesh será convertido em uma malha de navegação. O nó original da Malha será removido no momento da importação.

Cria um Veículo (-vehicle)

A mesh node with the -vehicle suffix will be imported as a child to a VehicleBody3D node.

Crie uma Roda de Veículo (-wheel)

A mesh node with the -wheel suffix will be imported as a child to a VehicleWheel3D node.

Rigid Body (-rigid)

A mesh node with the -rigid suffix will be imported as a RigidBody3D.

Loop de animação (-loop, -cycle)

Animation clips in the source 3D file that start or end with the token loop or cycle will be imported as a Godot Animation with the loop flag set. Unlike the other suffixes described above, this does not require a hyphen.

No Blender, isso requer o uso do Editor NLA e nomear a Ação com o prefixo ou sufixo loop ou cycle.

Material alpha (-alpha)

A material with the -alpha suffix will be imported with the TRANSPARENCY_ALPHA transparency mode.

Material vertex color (-vcol)

A material with the -vcol suffix will be imported with the FLAG_ALBEDO_FROM_VERTEX_COLOR and FLAG_SRGB_VERTEX_COLOR flags set.
