mix material need help to understand

[hedphelym]

Hi, I'm trying to understand how the mix material should be implemented.
(I'm working on the Luxmax exporter).

I have no experience with blender what so ever - so I'm not able to get my answer from there.

Let's say I have a scene, 3 boxes.
box A - B - C

A material = Glass
B material = Metal
C material= Mix of these two.

How does C's material definition look like?

My two boxes has the following:

Box A

Code: Select all

Material "glass" "color Kr" [1.000000 1.000000 1.000000]
"color Kt" [1.000000 1.000000 1.000000]
"float index" [1.000000]
"bool architectural" ["false"]


Box B

Code: Select all

Material "metal"
   "string name" ["aluminium"]
"float vroughness" [0.001000]
"float uroughness" [0.001000]


Thanks in advance.
