Shaders with presets for real-world reflectance values

I don't know if actually this make sense to the maxwell technology, but I was thinking, if maxwell is the most physically accurate renderer available, it would be good to have some control over the reflectance values, based in real-world materials, specially in diffuse shaders.

I mean, it could have presets for masonry, fabric, paper, stone, paint, etc. , each one with the correct physic value for reflectance and absorption.

Regards,

p.s. BTW, I don't know if tweaking the absorption and scattering values for the diffuse shaders make any difference in the rendering, right know, or if it's a future implementation.

Hi,

is also think this is necessary.
In Lightscape you can choose the settings from a small libary whitch setup
the physical attributes. Than you have only to load a bitmap for the texture
and do some work on the bump.

Flingster...I agree. I saw the post you mentioned and it motivated me to try my hand at using the Maxwell plastic material to get a particular look. Take a look at the post in the Maxwell Render forum section called "Stonehenge" and tell me what you think. I had some difficulty achieving the appearance I wanted. Specularity didn't work as I had been accustomed to in other renderers, but it's a start.

i hope there ll be plenty of materials preset first of all to make the mat set up easilly and to help us learn how to modify them for our need
