Lights and reflections

[jay-morales]

Hi,
I am wondering if any one has any ideas on how to vary the intensity of a reflection map of a shader depending on the amount of light hitting it.
Scene eg..
I have a airoplane, so lots of curves with a distant light "sun" behind it and other fill lights. The "sun" is the light that I want to effect the shaders reflection map. Also another benefit would be to vary the color intensity of the reflection according to the direction and intesity of the light.
I am using SLIM, MTOR....
thanks in advance..

You can do it by writing yours template for distant env. ligth...

For it you may combine env. ligth and distant ligth. models... All model for slim template we have in %rattree/lib/slim/ligth.slim template file.

For doing this :

1. Read RAT doc. for template writing

2. Main feature of env. ligth it is special output attr. such as __category= "environment" __nondiffuse =1 __nonspecular =1 simply use construction from env. ligth w/ combination construction from distant. ligth model (w/ fallo off by distant and else ....)
   Read this Shading Language Extensions for details.
