Hi all, I've been for a time out but now I want to return

I'm reading the manual and I have a question, I usually used the method

Color*Diffuse+Reflection+Translucency<100%.

All my works with kray have this form but I read that the other form

Color*Diffuse(100%-Transparency)+Transparency+Reflection+Translucency < 100%

is more correct. I would like to used this method but I don't understand really good the equation.

It is the same formula. The only difference is that in second formula you also have transparency included. What this basicaly means is that transparency takes away a diffuse component hence making object bounce back less light.

Usually your materials will have only some of the components like only transparency+color+reflection, or only translucency + color + reflection. So most of the time you don't have to worry about the complex formula
