Specifications: Shaders†

This section describes each shader.
Shaders should be changed according to what you want to achieve, so refer to this explanation and sample data to specify the shader you are looking for.

• Recommended Shaders
  General Background Models: a_n_rm
  Simple Textured Background Models: map
  Addition: map_nolit_add
  Translucent: map_nolit_alpha
  Glass: glass
  Water: transparent_normal_water
  Leaves Swaying in the Wind: map_wind_discard

Shader Descriptions†

• 2dmap_skybox
  Specify a background material with a 2D texture.
  The material with this shader selected will be available for selection in "Map Settings > Rendering > Background Material".

• a_n
  This shader uses physics-based shading with an albedo map and a normal map available for setting.

画像入る

• a_n_discard
  This shader uses physics-based shading with an albedo map and a normal map available for setting.
  It is also possible to use the alpha channel of an albedo map to discard alpha.

画像入る

• a_n_rm
  This shader uses physics-based shading with an albedo map, a normal map and a mask map available for setting.
  This is the recommended shader when using physics-based shading in Bakin.

画像入る

• a_n_rm_discard
  This shader uses physics-based shading with an albedo map, a normal map and a mask map available for setting.
  It is also possible to use the alpha channel of an albedo map to discard alpha.

画像入る

• a_n_rm_sss_discard
  This shader uses physics-based shading with an albedo map, a normal map and a mask map available for setting.
  It is also possible to use the alpha channel of an albedo map to discard alpha.
  In addition, the use of SSS (Subsurface Scattering) mask map allows for the rendering of light transparency.

• a_n_rm_wind_discard
  This shader uses physics-based shading with an albedo map, a normal map and a mask map available for setting.
  It is also possible to use the alpha channel of an albedo map to discard alpha.
  In addition, you can specify swaying effects in the wind.
  When using with grass growing on the ground, turn on "Fix Y=0".

画像入る

• a_n_wind_discard
  This shader uses physics-based shading with an albedo map and a normal map available for setting.
  It is also possible to use the alpha channel of an albedo map to discard alpha.
  In addition, you can specify swaying effects in the wind.
  When using with grass growing on the ground, turn on "Fix Y=0".

画像入る

• character_create_hair
  This is a special shader, a hair shader for characters, used in the Bakin sample character models.
  Overlay composite of vertex color and parameter hair color.

画像入る

• character_create_skin
  This is a special shader, a skin shader for characters, used in the Bakin sample character models.
  Parts such as eyes and mouth are placed from the vertex coordinates based on the parameters.

画像入る

• cubemap_skybox
  Specify a background material with a texture in .hdr format.
  The material with this shader selected will be available for selection in "Map Settings > Rendering > Background Material".

画像入る

• glass
  It renders a glass-like effect.

画像入る

• map
  It is a physics-based extension of a shader from a non-physical based rendering.
  Color textures can be specified.

画像入る

• map_discard
  Based on the map shader, discarding the alpha (non-transparent).
  It can be used for leaves and etc.

画像入る

• map_nolit
  This is a shader that does not perform lighting and does not apply an environment map, but displays the color of the texture as it is.
  Rendered as opaque.

画像入る

• map_nolit_add
  No lighting or environment map is applied, and the texture is blended with the color of the texture as it is by addition.
  Rendered as translucent.

画像入る

• map_nolit_alpha
  No lighting or environment map is applied, and the texture is composited with the texture's alpha value, using the texture's color as it is.
  Rendered as translucent.

画像入る

• map_nolit_discard
  Based on the map_nolit shader, discarding the alpha (non-transparent).
  Rendered as opaque.

画像入る

• map_nolit_modulate
  No lighting or environment map is applied, and the texture is blended by modulate, using the color of the texture as it is.
  Rendered as translucent.

画像入る

• map_notex
  Displays polygons using only vertex colors, without textures.
  Performs physics-based shading.
  Rendered as opaque.
  画像入る

• map_wind_discard
  This shader adds vertex animation by wind to map_discard.
  When using with grass growing on the ground, turn on "Fix Y=0".
  画像入る

• transparent_normal_water
  Use a normal map to render the water surface.
  The result of the back drawing is used for the refraction effect.
  画像入る

• Transparency Distance: This is the degree of underwater murkiness. The opacity of the water gradually increases from the surface to the transparency distance.
  画像入る

• Blend Distance: This is the distance where the transparency changes from 0 to 1 in the composition of the junction with the shore. 0 makes the touching of the ground clear.
  画像入る

• Opaque Distance: The distance until the "Transparency Distance" and "Blend Distance" become invalid with regard to the camera position. The higher this value, the more the effects of "Transparency Distance" and "Blend Distance" do not disappear even when the camera is moved away.

画像入る

• Water Fall Speed: When this shader is applied to a mesh extending in the Y direction, water will flow from top to bottom like a waterfall, and to specify the speed at which the water surface falls.

• Water Flow Direction: Specify the direction of water flow in 360 degrees.
