Sub-Surface Scattering Plug in |
![]() |
About this plug in.
Preface
This is a Lightwave Layout plug-in that uses its own raytracing algorithms to render
objects made of permeable materials.
It can produce many effects including Sub-surface Scattering.
Due to the fact that this plug-in uses its own raytracing algorithms there are some
problems with Lightwaves own radiosity.
There is also the problem that other plug-ins that perform their own raytracing may not
function with this plug-in.
Plug in name
OGO_Hikari (well, hikari is Japanese for "light" so there you go!)
Main function list
1. Sub-Surface Scattering.
2. Chromatic aberration in refraction.
3. Raytraced colour aberations based on the thickness of transparent surfaces.
4. Caustics per surface. (can use it for soft shadow)
5. Radiosity per surface.
6. New/unique specular algorithm.
7. Simple fresnel.
8. Soft reflection.
9. Soft refraction.
10. UV map based normal ray displacement.
11. Diffusion curve adjustment.
12. Transparency amout of undercoat of fuzzy materials (woolen sweater for example).
13. Designation of a color in a ray trace limit.
14.Multilayered specular.
15.Volumetric texture.
16.Three kinds of special light of OGO_Hikari exclusive use.
Characteristic
1. Default parameters result in a normal render as if rendered with Lightwave's raytracing
light wave oneself.
2. Ability to preview most functions in modeler (as well as of course layout).
3. Even some settings that would not mormally be physically acceptable in the real world
can be achieved.
4. The plug-in panel is devided into groups which can be ignored or used as required
making quick adjustments easy.
Future plan
Writing of a manual with hints and tips (this is going to be a lot of work!)
Start porting to the Mac.
Panel image
A panel image and rough explanation (for Version 1.13)
Added brief description of the parameters.

Object light Kougen\Object.lws |
![]() |
Movie(MPEG) |
Add OGO_Kougen of a custom object to an object to use as a light source, and
set a parameter of Object_light. By the technique that resembled radiosity, can use an arbitrary object as a light source. Even radiosity can get a result almost same as this image, but time of rendering is necessary for several times in order to get a result of the same quality. Cannot verify that influence of this light by a preview of a surface editor. |
Vertex light Kougen\Vertex.lws |
![]() |
Movie(MPEG) |
Add OGO_Kougen of a custom object to an object to use as a light source, and
set a parameter of Vertex_light. Be material to use it in the purpose that resembled an object light, but assign a point light to a vertex of an object, and process it. There is a little occurrence of a rendering noise when compares it with an object light. But please try to give numerical value of Fuzzy because shadow of an individual vertex light with a few vertex number has been divided clearly when it is inconvenient. In that case, a rendering noise of a certain level occurs. |
Particle light Kougen\Particle.lws or Kougen\Particle_for6.lws |

Add OGO_Kougen of particle and a custom object to a Null object to use as a

[Shading noise reduction] is off? [Intaraction mode] is Low interaction. [Specular calculate] is off. Apply Simple Fransel to an object of the left, and use Caustics(OGO_Hikari) for a soft shadow. |

[Shading noise reduction] is off [Intaraction mode] is Ragular interaction. [Specular calculate] is off. OGO_Hikari processes many nexts radiation if uses Ragular interaction or High interaction. |

Be the images which did rendering with a file the same as the
basically left image, but adjust setting of noise reduction to version 1.22, and be
changed. Because improved algorithm of noise reduction of version 1.22, both picture and rendering speed was improved. |

When combines OGO_Hikari and radiosity of LightWave
