TranVol 2

instructions:

The shader GUI remains largely unchanged and the majority of instructions from the previous page work.

There are a couple of additions however...

Surface illumination

Ambient Occlusion:

Enable - activates the effect

Detail - Increases the sampling and thus detail

Spread - Controls how much to divert the rays from the surface

0 = no spread, 1 = 90 degree spread

Distance - Specifiy the distance from which to check for ambient occlusion

useful if you want to ignore sky domes, etc

Amplitude - Controls the amount of the effect

Sub Surface Illumination

The light list has been removed due to the full inclusion of the light's own shader.

Scattering - controls mulitple scattered ray sampling

this option is a brand new addition which also includes light entering behind the object

...early days with this bit but deactivating the scattering effect removes this option...

Sampling - controls the amount of sample scatters

Diversion - dictates the diversity of scattering rays

0 = no diversion, 1 = 90 degree scattering

Fixes And Enhancements:

Transparency bug fixed

Stability Improved

Light shader inclusion:
E.g.
lights now control SSI shadows
light colors now affect SSI
light intensity has an effect

Directional Lights inclusion

Passes now work

Multiple lights now work

Speed ups to reduce marching in areas of no effect

Alpha channel fix for transparency

Lights influencing tranvol2 do not crash xsi when hidden

Ambient Occlusion now incorporated

Multiple Scattering now started

Linux Random sampling error
