Can Different Objects Use Different Camera Effects Unity

Photographic camera

Switch to Scripting

Cameras are the devices that capture and display the world to the role player. Past customizing and manipulating cameras, you tin can make the presentation of your game truly unique. You tin accept an unlimited number of cameras in a scene. They can exist prepare to render in any order, at any place on the screen, or only sure parts of the screen.

Properties

*Property:*	*Role:*
Articulate Flags	Determines which parts of the screen volition be cleared. This is handy when using multiple Cameras to depict dissimilar game elements.
Background	The color practical to the remaining screen after all elements in view accept been drawn and there is no skybox.
Culling Mask	Includes or omits layers of objects to be rendered by the Photographic camera. Assigns layers to your objects in the Inspector.
Projection	Toggles the camera's adequacy to simulate perspective.
Perspective	Camera volition render objects with perspective intact.
Orthographic	Photographic camera will render objects uniformly, with no sense of perspective. NOTE: Deferred rendering is not supported in Orthographic mode. Forrad rendering is always used.
Size (when Orthographic is selected)	The viewport size of the Photographic camera when set to Orthographic.
Field of view (when Perspective is selected)	The width of the Camera's view angle, measured in degrees along the local Y centrality.
Clipping Planes	Distances from the photographic camera to get-go and stop rendering.
Near	The closest point relative to the camera that drawing will occur.
Far	The furthest point relative to the camera that drawing will occur.
Viewport Rect	Four values that indicate where on the screen this camera view will be drawn. Measured in Viewport Coordinates (values 0–i).
X	The starting time horizontal position that the photographic camera view volition be drawn.
Y	The beginning vertical position that the camera view will be fatigued.
W (Width)	Width of the camera output on the screen.
H (Height)	Height of the camera output on the screen.
Depth	The photographic camera'southward position in the draw order. Cameras with a larger value will be drawn on top of cameras with a smaller value.
Rendering Path	Options for defining what rendering methods will exist used by the photographic camera.
Use Player Settings	This photographic camera will utilize whichever Rendering Path is set in the Player Settings.
Vertex Lit	All objects rendered by this camera will be rendered as Vertex-Lit objects.
Forwards	All objects will be rendered with i pass per material.
Deferred Lighting	All objects will be drawn in one case without lighting, then lighting of all objects will be rendered together at the terminate of the render queue. NOTE: If the photographic camera's projection manner is set to Orthographic, this value is overridden, and the camera will always use Forward rendering.
Target Texture	Reference to a Render Texture that will incorporate the output of the Camera view. Setting this reference will disable this Camera'south capability to render to the screen.
HDR	Enables High Dynamic Range rendering for this camera.
Target Display	Defines which external device to return to. Between 1 and 8.

Details

Cameras are essential for displaying your game to the player. They tin can be customized, scripted, or parented to achieve only about any kind of outcome imaginable. For a puzzle game, you might keep the Camera static for a full view of the puzzle. For a first-person shooter, you would parent the Camera to the histrion character, and place information technology at the character's eye level. For a racing game, you'd probably have the Camera follow your player'due south vehicle.

You lot tin create multiple Cameras and assign each one to a different Depth. Cameras are drawn from low Depth to high Depth. In other words, a Camera with a Depth of 2 volition be fatigued on peak of a Camera with a depth of ane. You tin accommodate the values of the Normalized View Port Rectangle property to resize and position the Camera'south view onscreen. This can create multiple mini-views like missile cams, map views, rear-view mirrors, etc.

Render path

Unity supports different rendering paths. Yous should choose which one you use depending on your game content and target platform / hardware. Different rendering paths have different features and performance characteristics that mostly impact lights and shadows. The rendering path used by your project is chosen in Player Settings. Additionally, yous can override it for each Camera.

For more data on rendering paths, bank check the rendering paths page.

Articulate Flags

Each Photographic camera stores color and depth information when it renders its view. The portions of the screen that are not drawn in are empty, and will display the skybox by default. When you lot are using multiple Cameras, each ane stores its own color and depth information in buffers, accumulating more than data equally each Camera renders. As any particular Camera in your scene renders its view, y'all tin set the Clear Flags to clear different collections of the buffer data. To do this, cull 1 of the following four options:

Skybox

This is the default setting. Any empty portions of the screen will display the current Camera's skybox. If the current Photographic camera has no skybox fix, it will default to the skybox chosen in the Lighting Window (menu: Window > Lighting). It volition then autumn back to the Background Colour. Alternatively a Skybox component can be added to the camera. If yous want to create a new Skybox, you can use this guide.

Solid colour

Any empty portions of the screen volition display the electric current Camera's Groundwork Color.

Depth only

If you lot want to draw a role player'southward gun without letting it get clipped inside the environment, gear up ane Camera at Depth 0 to draw the surroundings, and some other Camera at Depth one to draw the weapon alone. Gear up the weapon Camera's Clear Flags to depth just. This will continue the graphical brandish of the environment on the screen, but discard all data about where each object exists in 3-D space. When the gun is drawn, the opaque parts volition completely cover anything fatigued, regardless of how close the gun is to the wall.

The gun is drawn last, after clearing the depth buffer of the cameras before it — The gun is drawn final, after clearing the depth buffer of the cameras earlier it

Don't clear

This style does not clear either the colour or the depth buffer. The result is that each frame is drawn over the next, resulting in a smear-looking effect. This isn't typically used in games, and would more than likely be used with a custom shader.

Annotation that on some GPUs (mostly mobile GPUs), not clearing the screen might outcome in the contents of it beingness undefined in the next frame. On some systems, the screen may incorporate the previous frame epitome, a solid blackness screen, or random colored pixels.

Clip Planes

The About and Far Clip Plane backdrop determine where the Camera'south view begins and ends. The planes are laid out perpendicular to the Camera'southward direction and are measured from its position. The Well-nigh plane is the closest location that will be rendered, and the Far plane is the furthest.

The clipping planes likewise make up one's mind how depth buffer precision is distributed over the scene. In general, to get ameliorate precision you should move the About plane as far as possible.

Annotation that the near and far clip planes together with the planes defined by the field of view of the camera describe what is popularly known as the photographic camera frustum. Unity ensures that when rendering your objects those which are completely exterior of this frustum are not displayed. This is chosen Frustum Culling. Frustum Culling happens irrespective of whether you use Occlusion Alternative in your game.

For functioning reasons, yous might want to choose small objects earlier. For instance, small rocks and debris could be made invisible at much smaller distance than large buildings. To do that, put minor objects into a carve up layer and gear up upwardly per-layer choose distances using Camera.layerCullDistances script function.

Alternative Mask

The Culling Mask is used for selectively rendering groups of objects using Layers. More information on using layers tin be found here.

Normalized Viewport Rectangles

Normalized Viewport Rectangle is specifically for defining a certain portion of the screen that the current camera view will be drawn upon. You lot can put a map view in the lower-right manus corner of the screen, or a missile-tip view in the upper-left corner. With a bit of blueprint work, yous can use Viewport Rectangle to create some unique behaviors.

Information technology's easy to create a ii-player split screen effect using Normalized Viewport Rectangle. Afterward y'all accept created your two cameras, change both camera's H values to be 0.five then set player i'southward Y value to 0.5, and player two's Y value to 0. This volition make role player one's photographic camera brandish from halfway upwards the screen to the superlative, and player two's photographic camera kickoff at the bottom and finish halfway up the screen.

Orthographic

Marking a Photographic camera as Orthographic removes all perspective from the Photographic camera'south view. This is mostly useful for making isometric or second games.

Annotation that fog is rendered uniformly in orthographic camera mode and may therefore not announced equally expected. This is because the Z coordinate of the post-perspective space is used for the fog "depth". This is not strictly accurate for an orthographic camera but it is used for its performance benefits during rendering.

Render Texture

This will place the camera's view onto a Texture that can then be practical to another object. This makes it easy to create sports arena video monitors, surveillance cameras, reflections etc.

Target display

A camera has up to eight target display settings. The camera can be controlled to render to ane of up to 8 monitors. This is supported but on PC, Mac and Linux. In Game View the called brandish in the Camera Inspector will be shown.

Hints

Cameras can be instantiated, parented, and scripted but like any other GameObject.
To increment the sense of speed in a racing game, utilise a high Field of View.
Cameras can be used in physics simulation if you add a Rigidbody Component.
There is no limit to the number of Cameras y'all can have in your scenes.
Orthographic cameras are great for making 3D user interfaces.
If you are experiencing depth artifacts (surfaces close to each other flickering), try setting Near Plane to every bit big every bit possible.
Cameras cannot render to the Game Screen and a Return Texture at the aforementioned time, but 1 or the other.
There's an choice of rendering a Camera's view to a texture, called Render-to-Texture, for even more interesting furnishings.
Unity comes with pre-installed Camera scripts, constitute in Components > Photographic camera Control. Experiment with them to become a taste of what's possible.
