Indigo Renderer Forum

just messing around with specular material with basic medium and I'm noticing that translation of Absorption R-G-B + gain from Blender to Indigo is not in a way I'd expect:

Blendigo settings: [R]0.9 - [G]0.4 - 0.1 - [gain]10.0
Indigo: 0.111111137786 - 0.666666661148 - 1.0 - 8.999999985099

Blendigo settings: 0.9 - 0.4 -0.4 - 10.0
Indigo: 0.166666708059 - 1.0 - 1.0 - 5.999999940395

Blendigo settings: 0.1 - 0.4 -0.4 - 10.0
Indigo: 1.0 - 0.606060599903 - 0.606060599903 - 9.900000002235

bug? doing it wrong? I can reproduce this on a fresh default blender scene.
I'm using blender 2.69 - blendigo 3.6.25.0 - Indigo 3.8.1

here's a pic of the scene I'm tinkering with. For now just modifying material values in indigo itself. My goal is just to wrap my head around how to adjust transparent materials so I can use them more easily in complex renders without rerendering so many times simply for the sake of material adjustment. "1M" is actually .1 blender units or 10cm.
