Radiance Materials outputs problems

Hello Mostapha,

I am trying to understand few things regarding the Radiance custom made materials.

  1. Metal: Shouldn t the specularity be above roughness in the inputs? The output comes out that way anyways.

  2. transMaterials: Should the sequence follow that sequence? 7 red green blue spec rough trans tspec?

I get output number different from the inputs as seen in the attached.

Hi Dimitrios,

  1. The output is correct and specularity comes first (http://www.artifice.com/radiance/rad_materials.html). The order was a user interface decision and since we have it like this in all the other components I would leave it as it is.

  2. It’s a bit more complicated. You can read more here (http://radiance-online.org/community/workshops/2010-freiburg/PDF/Da…). Orn also made a good description based on this presentation (http://www.grasshopper3d.com/group/ladybug/forum/topics/radiance-bl…).
