ShaderNodeEnvironmentΒΆ

Reads a environment texture file. This node returns the filtered RGB/RGBA pixel value from a environment texture file, using a direction.

Preview

Shows a preview of the environment.

Mode

Changes the transform mode to use for the environment lookup. The modes include :

  • Local : Assumes the input coordinate is in camera space, linking the environment to the camera.
  • World : Transforms the input coordinate from camera space to world space, linking the environment to world.

Filename

Environment texture filename.

Filter

Changes texel filtering function. The functions include :

  • Box : Selects nearest texel. May produce aliased results.
  • Triangle : Uses a simple triangle filtering function.
  • Gaussian : Uses a windowed gaussian filtering function.
  • BSpline : Uses a radial BSpline filtering function. Should be used for displacement maps.

Size

Limits the size of the environment texture in memory.

Width

Scales the filtering window of the lookup.

Blur

Minimum filtering window of the lookup.

Gamma

Gamma correction at environment texture lookup. This value can be drived by the project Gamma setting, or individually per environment texture.

Build Texture

Generates the block ordered tiled texture. Textures always need to be built prior use. Built textures are located in the hidden .guerilla directory next to the source bitmap file.

Render Pass

Opens a linking view in the FileIn<->RenderPass mode.

Output

Selects the connected pass output to read from.
