Please find below the link to the first material:http://www.indigorenderer.com/materials/materials/1069How to make a correct SKN 165 window model:
The product must be assembled in a double glazing unit configuration. This consists in two glass pane of thicknesses ranging from 6mm to 10mm. The two panes are separated by a gas space of generally 15-16mm (Argon gas, but can be modelled as air).
The two glass panes are applied the SGG Planilux material found here : http://www.indigorenderer.com/materials/materials/1026
The coated glass material must be applied to the side of the outer pane facing the gas space
. This is very important to achieve proper colors, as the product color have been designed for this configuration. This breaks the classical rule "the specular material must be applied to all faces of a closed shape", but still works perfectly as both materials (Planilux and SKN165) share the same medium (as the coating is deposited on a Planilux base glass)
Last, and very important to make everything work, you must delete the "sgg-planilux" from the material file, and ensure that the Planilux igm is included before in the scene. This is because indigo is currently not accepting a medium being redefined, without unpredictable behavior. This issue has been adressed to glare and should be corrected soon to ensure much easier integration of these complex materials.
Awaiting your feedback before uploading more coatings!
