If the layerMask = 0, we will never find any collisions with the ray. If all bits in the layerMask are on, we will collide against all colliders. The Physics.Raycast function takes a bitmask, where each bit determines if a layer will be ignored or not. Using layers you can cast rays and ignore colliders in specific layers.įor example you might want to cast a ray only against the player layer and ignore all other colliders. Screen space canvas children do not respect the camera’s culling mask. More info See in Glossary elements aren’t culled. Modify the culling mask by checking or unchecking layers in the culling mask property.īe aware that UI (User Interface) Allows a user to interact with your application. To do this, select the camera that should selectively render objects. See in Glossary, you can selectively render objects which are in one particular layer. Using the camera’s culling mask Allows you to include or omit objects to be rendered by a Camera, by Layer.

Drawing only a part of the Scene with the Camera’s culling mask In the Tags and Layers window, the Player layer is assigned to layer 8. Now that you have created a new layer, you can assign the layer to one or more GameObjects.Įach GameObject can only be assigned one layer. We create a new layer in one of the empty User Layers. To create a new layer, open the Tags and Layers window (main menu: Edit > Project Settings, then select the Tags and Layers category). A GameObject’s functionality is defined by the Components attached to it. The first step is to create a new layer, which we can then assign to a GameObject The fundamental object in Unity scenes, which can represent characters, props, scenery, cameras, waypoints, and more. More info See in Glossary or to create collisions A collision occurs when the physics engine detects that the colliders of two GameObjects make contact or overlap, when at least one has a Rigidbody component and is in motion. A collider doesn’t need to be exactly the same shape as the object’s mesh - a rough approximation is often more efficient and indistinguishable in gameplay. But they can also be used by raycasting to selectively ignore colliders An invisible shape that is used to handle physical collisions for an object. More info See in Glossary, and by Lights to illuminate only parts of the scene. In each Scene, you place your environments, obstacles, and decorations, essentially designing and building your game in pieces. Think of each unique Scene file as a unique level. More info See in Glossary to render only a part of the scene A Scene contains the environments and menus of your game. The output is either drawn to the screen or captured as a texture. They are most commonly used by Cameras A component which creates an image of a particular viewpoint in your scene. This study paves the way for innovation in the manufacturing of ceramic products by 3D printing as an alternative to the traditional ceramic process.Layers in Unity define which GameObjects can interact with different features and one another. In addition, gear-shaped objects with different-colored layers of ceramic resins were successfully manufactured by continuous 3D printing and simultaneous sintering. The different-colored 3D-printed 3Y-ZrO 2 objects sintered at 1450 ☌ for 180 min exhibited a high relative density of>99.90% and a high flexural strength of>930 MPa, which are comparable to those of commercial 3Y-ZrO 2 manufactured by a conventional ceramic process. Thus, white, pink, yellow, and gray 3Y-ZrO 2 ceramic nanocomposite resins with optimum physical properties were prepared. Based on the correlation between the solubility parameters of UV-curable organic resin systems and the rheological behaviors of highly loaded ceramic nanocomposites, the physical properties of the different-colored 3Y-ZrO 2 ceramic nanocomposite resins, such as photocurability, viscosity, flowability, and printability, were optimized for a supportless 3D printing process.

UV-curable different-colored 3Y-ZrO 2 ceramic nanocomposite resins with a ceramic content of 50 vol% were prepared for supportless stereolithography 3D printing.
