envCube

Go to: Related nodes. Attributes.

The EnvCube texture creates a cubic texture map for use as an environment map. The effect is like placing a reflective object inside a cube with an image on each face. The object will reflect those images. You can select what images or textures are mapped onto each face of the Env Cube.

To use this texture as an environment map, connect its Out Color attribute to the Reflected Color attribute of any specular shader, such as Blinn or Phong..

Aside from the attributes listed here, EnvCube inherits additional attributes from TextureEnv.

In the table below, important attributes have their names listed in bold in the description column.

Long name (short name)	Type	Default	Flags
back (ba)	float3	0.0, 0.0, 0.0
Back is the image that is mapped onto the back side of the EnvCube.
backR (bar) float 0.0 The red component of Back
backG (bag) float 0.0 The green component of Back
backB (bab) float 0.0 The blue component of Back
bottom (bo)	float3	0.0, 0.0, 0.0
Bottom is the image that is mapped onto the bottom side of the EnvCube.
bottomR (bor) float 0.0 The red component of Bottom
bottomG (bog) float 0.0 The green component of Bottom
bottomB (bob) float 0.0 The blue component of Bottom
front (fr)	float3	0.0, 0.0, 0.0
Front is the image that is mapped onto the front side of the EnvCube.
frontR (frr) float 0.0 The red component of Front
frontG (frg) float 0.0 The green component of Front
frontB (frb) float 0.0 The blue component of Front
infiniteSize (ie)	bool	0
Infinite Size. If this is turned on, then the images in the cube will be reflected as though the sides of the cube were infinitely far away. If you are using images of distant things, such as the horizon or a starfield, turn on Infinite Size. If the images are of the interior of a room, or nearby objects, leave Infinite Size off.
infoBits (ib)	integer	0
Information bits passing along information about type of shading
left (le)	float3	0.0, 0.0, 0.0
Left is the image that is mapped onto the left side of the EnvCube.
leftR (ler) float 0.0 The red component of Left
leftG (leg) float 0.0 The green component of Left
leftB (leb) float 0.0 The blue component of Left
lookupType (lt)	enum	0
Determines how the texture should be looked up in the cube map and is currently only support by the hardware renderer. The default is the reflection vector look up. Normal uses the normal vector versus the reflection vector.
pointWorld (pw)	float3
The input point
pointWorldX (pwx) float 0.0 The X component of the input point
pointWorldY (pwy) float 0.0 The Y component of the input point
pointWorldZ (pwz) float 0.0 The Z component of the input point
right (ri)	float3	0.0, 0.0, 0.0
Right is the image that is mapped onto the right side of the EnvCube.
rightR (rir) float 0.0 The red component of Right
rightG (rig) float 0.0 The green component of Right
rightB (rib) float 0.0 The blue component of Right
top (to)	float3	0.0, 0.0, 0.0
Top is the image that is mapped onto the top side of the EnvCube.
topR (tor) float 0.0 The red component of Top
topG (tog) float 0.0 The green component of Top
topB (tob) float 0.0 The blue component of Top
