====== Reflection (DED) ======

Any surface (flats or walls) can be rendered with [[shiny surface]] properties. This allows for some very interesting tricks to be created such as specular "reflections". You can use a mask with the shiny surfaces to mask out areas of shininess but a mask can be used to also increase the effect of shininess on areas of a texture. Reflection definitions support the use of any of the new blending mode flags such as add and subtract.


===== Syntax =====

  Reflection
  {
     Texture = "";
         # The wall texture this reflection will be associated with. A 
         # reflection can only be associated with either a texture or a 
         # flat, not both.
     Flat = "";
         # The flat this reflection will be associated with.
     Flags = flaga | flagb | flagc etc...
         # NEW in 1.9.0-beta6
         # noiwad: Don't use this reflection if the resource is loaded from an IWAD.
         # pwad: This reflection can be used with PWAD resources (for example custom textures).
         # ext: This reflection can be used with external resources.
     Blending mode = add;
         # One of the bm_* flags defined in Flags.ded. By default 
         # reflections use additive blending.
     Shininess = 1.0;
         # Strength of the shiny effect. 1.0 is the maximum value. This
         # is used as the alpha component when doing blending.
     Min color { 0.0 0.0 0.0 }
         # By default the shiny effect uses sector light as the basic color
         # of the effect. The Min color RGB values (0..1) can be used to
         # set a minimum light level for the effect so it'll show up even
         # in very dark sectors.
     Shiny map = "";
         # Name of the external resource that is used as the shiny map for
         # this reflection. By default the resource is searched in the
         # LightMaps resource directory. The shiny map is mapped onto 
         # reflecting surfaces using a mapping that resembles cylindrical
         # environment mapping. The dimensions of the map must be powers
         # of two, for example 128 x 64 or 32 x 128.
     Mask map = "";
         # Name of the external resource that is used to mask out the 
         # shininess of a surfaces. The mask map is mapped onto surfaces 
         # using the same texture coordinates that are used for mapping 
         # regular textures. The darker the texel in the mask, the fainter
         # the reflection becomes. The dimensions of the map must be powers
         # of two, for example 128 x 64 or 32 x 128.
     Mask width = 1.0;
         # A factor for the width of the mask. This can be used to make the
         # mask span beyond the mapping of the regular texture of the 
         # surface. For example, consider a surface with a texture that is
         # 64 texels wide. Regardless of the mask's horizontal resolution,
         # the mask is always mapped onto the regular texture so that their
         # edges overlap. If the mask width value is 1.0, the mask is as 
         # wide as the 64 texel original texture. If mask width is increased 
         # to 2.0, the mask is mapped so that it is as wide as a 128 texel 
         # texture.
     Mask height = 1.0;
         # A factor for the height of the mask.
