You mean shaders from Kray?
Now are 3 shaders from Kray, all shader I use in my renders becouse they help me strong.
1/KrayIndirectRays
desaturate: 100% make white (gray) bounce color information (very good for wood floor ) they reduce colored on wall and ceiling past bounce light sun.
Ideal 50-100%, 0% is OFF.
Multiply: I don`t use this, but if You need: no problem (extra bounce lights for surface) same Multiplier in Kray. Sometimes I use it for lumi poly (they make stronger shadow, contrast, light) good is 2-3, but You can use 10.
Limit dynamic range: experimental shader (make fantastic light from small lumi poly without strong blum near lumi poly) This is hard for use....
2/KraySkyPortal
My favorite
Make fantastic photons position, very "inteligent" shader. They collect light from outside area and shot item to room but....very "inteligent" - reduce strong light near windows, make very good contrast, make very good light around obiects. This is best shader from Kray. I use only this for lights inside rooms, small lights to.
Importance must be 100%, Visible make loooooong render - You don`t need this. Caustic portal for caustic effect if You need.
3/KraySurfaceOption
Control diffuse model : turn ON this shader
It is individual control FG for surfaces. Good for leavs on tree (You don`t need good FG on leavs becouse they is far). Good for far obiects.
Control FG need turn ON, You can use very low setup for far obiect: 20/50 or similar. For very far obiects You can use: Diffuse model - photon filtered without Control FG Rays.
