RenderTexture

View source
Object → Texture → unityengine.RenderTexture (extern class)

A texture that can be rendered to by cameras or used as a render target. RenderTextures enable off-screen rendering for post-processing effects, mirrors, minimaps, and render-to-texture operations.

In Ceramic's Unity backend, RenderTextures are used for:

  • Implementing render-to-texture functionality
  • Creating dynamic textures at runtime
  • Post-processing effects and filters
  • Capturing screen content

Key features:

  • GPU-based rendering target
  • Multiple format support (color, depth, stencil)
  • Can be used as regular textures after rendering
  • Supports anti-aliasing and HDR

Basic usage:

// RenderTextures are typically created and managed
// by Ceramic's backend for filters and effects
RenderTexture.active = myRenderTexture;
// Render operations here...
RenderTexture.active = null;
See: Texture, Camera

Static Members

unity
active: RenderTexture

The currently active render texture for drawing operations. All rendering commands target this texture until changed.

Set to a RenderTexture before rendering to draw into it. Set to null to render to screen/framebuffer.

Critical for render-to-texture operations:

var previous = RenderTexture.active;
RenderTexture.active = myRT;
// Render here
RenderTexture.active = previous; // Restore

Instance Members

unity
width: Int

Width of the render texture in pixels. Read-only after creation.

Should match the aspect ratio and resolution needs of your rendering use case.

unity
height: Int

Height of the render texture in pixels. Read-only after creation.

Common sizes:

  • Power of 2 for older hardware compatibility
  • Screen resolution for full-screen effects
  • Smaller for performance (e.g., 256x256 for minimaps)
unity
filterMode: FilterMode

Texture filtering mode when sampling. Affects visual quality when texture is scaled.

  • Point: Pixelated/nearest neighbor (retro look)
  • Bilinear: Smooth interpolation (default)
  • Trilinear: Smooth with mipmaps

For pixel-perfect rendering, use Point filtering.
