Render Textures are special types of TexturesAn image used when rendering a GameObject, Sprite, or UI element. Textures are often applied to the surface of a mesh to give it visual detail. More info
See in Glossary that are created and updated at runtime. To use them, you first create a new Render Texture and designate one of your CamerasA component which creates an image of a particular viewpoint in your scene. The output is either drawn to the screen or captured as a texture. More info
See in Glossary to render into it. Then you can use the Render Texture in a MaterialAn asset that defines how a surface should be rendered, by including references to the Textures it uses, tiling information, Color tints and more. The available options for a Material depend on which Shader the Material is using. More info
See in Glossary just like a regular Texture. The Water prefabsAn asset type that allows you to store a GameObject complete with components and properties. The prefab acts as a template from which you can create new object instances in the scene. More info
See in Glossary in Unity Standard AssetsA collection of useful assets supplied with Unity. Unity ships with multiple Standard Asset such as 2D, Cameras, Characters, CrossPlatformInput, Effects, Environment, ParticleSystems, Prototyping, Utility, and Vehicles. More info
See in Glossary are an example of real-world use of Render Textures for making real-time reflections and refractions.
The Render Texture InspectorA Unity window that displays information about the currently selected GameObject, Asset or Project Settings, alowing you to inspect and edit the values. More info
See in Glossary is different from most Inspectors, but very similar to the Texture Inspector.
The Render Texture inspector displays the current contents of Render Texture in realtime and can be an invaluable debugging tool for effects that use render textures.
|Dimension||The dimensionality (type) of the render texture.|
|2D||The render texture is two-dimensional.|
|Cube||The render texture is a cube map.|
|3D||The render texture is three-dimensional.|
|Size||The size of the render texture in pixelsThe smallest unit in a computer image. Pixel size depends on your screen resolution. Pixel lighting is calculated at every screen pixel. More info
See in Glossary. You can only enter power-of-two values, such as 128 and 256.
|Anti-Aliasing||The number of anti-aliasing samples. You can select None, 2 samples, 4 samples, or 8 samples. If you select None, Unity does not apply anti-aliasing.|
|Color Format||The color format of the render texture.|
|Depth Buffer||The format of the depth buffer. You can select No depth buffer, At least 16 bits depth (no stencil), or At least 24 bits depth (with stencil). The stencil buffer is a general purpose buffer that allows you to store an additional unsigned 8-bit integer (0–255) for each pixel drawn to the screen.|
|sRGB (Color RenderTexture)||Check this box to make the render texture use sRGB read/write conversions.|
|Enable Mip Maps||Check this box to make the render texture generate mipmaps.|
|Auto generate Mip Maps||Check this box to automatically fill the generated mipmaps with relevant data. If you don’t enable this, you’ll have to use the
|Dynamic Scaling||Check this box to let dynamic resolution scaling resize the render texture. If you don’t enable this, the render texture maintains the same size regardless of the Dynamic Resolution setting.|
|Wrap Mode||Controls how the texture is wrapped:|
|Repeat||Tiles the texture to create a repeating pattern.|
|Clamp||Stretches the edges of the texture. This is useful for preventing wrapping artifacts when you map an image onto an object and you don’t want the texture to tile.|
|Mirror||Tiles the texture to create a repeating pattern that mirrors the texture at every integer boundary.|
|Mirror Once||Mirrors the texture once, and then falls back to clamping.|
|Per-axis||Lets you set different wrap modes for the U axis and the V axis. The available options are also Repeat, Clamp, Mirror and Mirror Once. For example, when you use latitude-longitude environment maps for reflection probesA rendering component that captures a spherical view of its surroundings in all directions, rather like a camera. The captured image is then stored as a Cubemap that can be used by objects with reflective materials. More info
See in Glossary, it is useful to have Clamp on the vertical coordinate (V axis), but Repeat on the horizontal coordinate (U axis).
|Filter Mode||Controls how the sampling of the texture uses nearby pixels. The options are:|
|Point||Uses the nearest pixel. This makes the texture appear pixelated.|
|Bilinear||Uses a weighted average of the four nearest texels. This makes the texture appear blurry when you magnify it.|
|Trilinear||Uses a weighted average of the two nearest mips, which are bilinearly filtered. This creates a soft transition between mips, at the cost of a slightly more blurry appearance.|
|Aniso LevelThe anisotropic filtering (AF) level of a texture. Allows you to increase texture quality when viewing a texture at a steep angle. Good for floor and ground textures. More info
See in Glossary
|Anisotropic filtering level of the texture. This increases texture quality when you view the texture at a steep angle. Good for floor, ground, or road textures.|
