MR: DGS materials: default values

[nisus]

Hi All,

 

Does anyone knows about a list with DGS-values for most common materials?

 

I mean, what is the refraction ratio of asphalt, concrete, wood, ceramics,...?

How glossy are aluminium, brushed steel etc?

 

I don't find such a list. Any help helps ,-)

 

 

rgds,

ps: a DGS-material library would be even more awesome! ,-)

maybe start your material with a Architectural Material as ' template', and adjust the shaders in the Mental Ray Connexion rol-out.

Hi ajv,

 

This might be done for the refraction coordinate, but i think the 'shiny' (DGS) is not the same as 'shininess' (Arch.Mat)... and what about glossiness?

 

So anyone else got any ideas?
