[ART] Blender Reflection Texture

[GraphicsKid]

Diffuse is what color the texture is.
Specular is a map that defines how visible highlights are.
Height is used only for parallax occlusion mapped surfaces (like the walls). This is where it's really flat geometry, but the shader uses this height map to distort the texture coordinates to give you the impression that stuff is poking out or poking into a flat surface.
Cubemap is (if I'm not mistaken) a cube shaped map that wraps around the object to make fast, fake reflections (so I think THIS is what you're after)
Dissolve alpha - not sure.
NMap - a map that tells what direction the light should appear to strike the surface at. A way of faking detail in a flat polygon. NOT the same as a bump map. Bump maps are black and white and only give height, wheras normal maps give normal, or direction to the surface, and tend to be a light blueish color overall, with red and green bits showing direction.
Alpha - this is to make the surface partly transparent, like smoke, or say for example a leaf might be a flat polygon but with a round, white shape on black as an alpha channel.
Illumination - illuminates the object, ie it doesn't have to have a light on it to be visible. So this could be things like the inner glowing bits on a burning piece of wood.
Refraction - not sure what it means here in the hpl materia, but refraction IRL is when a transparent surface bends light, like water or glass.
