Render Texture
Render Textures are special types of Textures that are created and updated at runtime. To use them, you first create a new Render Texture and designate one of your Cameras to render into it. Then you can use the Render Texture in a Material just like a regular Texture. The Water prefabs in Unity Standard Assets are an example of real-world use of Render Textures for making real-time reflections and refractions.
Свойства
The Render Texture Inspector is different from most Inspectors, but very similar to the Texture Inspector.
The Render Texture Inspector is almost identical 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.
| Свойство: | Функция: |
|---|---|
| Size | The size of the Render Texture in pixels. Observe that only power-of-two values sizes can be chosen. |
| Anti-Aliasing | The amount of anti-aliasing to be applied. None, two, four or eight samples. |
| Depth Buffer | The type of the depth buffer. None, 16 bit or 24 bit. |
| Wrap Mode | Отвечает за поведение текстуры при тайлинге: |
| Repeat | Текстура повторят (тайлит) саму себя |
| Clamp | Края текстуры растягиваются |
| Filter Mode | Отвечает за то, как текстура фильтруется, если её растянуло при 3D трансформациях: |
| No Filtering | Вблизи текстура становится более пиксельной |
| Bilinear | Вблизи текстура становится более размытой |
| Trilinear | Как и Bilinear, но текстура также размывается и на разных мип уровнях |
| Aniso Level | При обзоре текстуры под крутым углом качество текстуры визуально улучшается. Хорошо подходит для текстур полов и земли. |

Описание
Render textures are textures that can be rendered to.
They can be used to implement image based rendering effects, dynamic shadows, projectors, reflections or surveillance cameras.
One typical usage of render textures is setting them as the «target texture» property of a Camera (Camera.targetTexture), this will make a camera render into a texture instead of rendering to the screen.
Another use case is manually implementing various rendering effects, for example Image Effects. There you often get temporary short-lived render textures (GetTemporary and ReleaseTemporary functions), and manually render objects into them (see Graphics.DrawMeshNow and Graphics.Blit).
Keep in mind that render texture contents can become «lost» on certain events, like loading a new level, system going to a screensaver mode, in and out of fullscreen and so on. When that happens, your existing render textures will become «not yet created» again, you can check for that with IsCreated function.
Render Texture
Render Textures are special types of Textures An 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 run time. To use them, you first create a new Render Texture and designate one of your Cameras A 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 Material An 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 prefabs An 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 Assets are an example of real-world use of Render Textures for making real-time reflections and refractions.
Properties
The Render Texture Inspector A 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 is almost identical 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.

| Depth Buffer | The type of the depth buffer. None, 16 bit or 24 bit. |
| Wrap Mode | Selects how the Texture behaves when tiled: |
| Repeat | The Texture repeats (tiles) itself |
| Clamp | The Texture’s edges get stretched |
| Filter Mode | Selects how the Texture is filtered when it gets stretched by 3D transformations: |
| No Filtering | The Texture becomes blocky up close |
| Bilinear | The Texture becomes blurry up close |
| Trilinear | Like Bilinear, but the Texture also blurs between the different mip levels |
| Aniso Level | Increases Texture quality when viewing the texture at a steep angle. Good for floor and ground textures |
