It looks to me that it's more like an adjustive layer then an overriding layer ...
Look at my example :
This is the normal material, taken from the library in VIZ4 and a little bit adjusted
Now when I make that material into an override material, keeping the old one, I get this :
See that both Reflectance and transmittance stay the same, when I use the standard settings of 1 in the override material. (So even if both are set to 1, I still do not have more then 100% light after the bounce then before ...)
Now when I change the Reflectance settings to 0,5 (They even call it SCALE, so it's a relative setting) I get this :
The reflectance result in half as much as I got before the change. It's not 50% (like in 0,5 = 50% of 1)
And yes maybe I should read the user guide, but I'm not the kind of reading guy
This just flashed thru my head when I was trying your settings ... (VERY good help btw! Thx alot, it realy helps)
Plz tell me if I'm making a mistake, I'm in a learning process
