Yeah, I know that I'm querying the 'sensitive' bits of the software. But if I can establish some equivalencies with existing published BRDF models it would be inordinately useful for me and the community that I work in.

I like the software, it's intuitive, speedy and comes with a seasoned ...

At the heart of my query is an attempt to understand what is happening when I'm changing a parameter like 'roughness' in the Glossy material options. One possibility is that a single measured BRDF is fit to some model that allows you to modify relevant parameters to generate new analytical BRDF's. A ...

All,

I'd like to be able to report BRDF details of the materials I'm using as stimuli in a study. I seem to have read that the Octane Render glossy material BRDF is held as proprietary. Can I import a BRDF to use? For example, can I use a reflectance function from the MERL BRDF database?

Thanks ...
