Ok, if you want some lulz, just search other forumsAs for the albedo: do this: Find one material where you are 99% sure you know its true albedo. It can be for example a list of paper (nontranslucent). Place it side by side to real world materials and observe from multiple angles - is the paper whiter? Then its albedo must higher. So you can establish upper/lower bounds on real world albedos.
have you seen this Juraj? http://patapom.com/topics/WebGL/BRDF/ it does the same as brdf explorer, but gives you control over lightning and materials. And shows you albedo values too ...It's a great webapp to play with. :) The albedo values there, when you load "white-paint" are about 0.75 (as a mean value, they do give you a value for each rgb channel), so I've been using this to try to imitate materials in Corona. The Diffuse Rho values are also very handy because they get red when it's over the value 1.

And it shows albedo value, quite lower than what I would expect.CG artists have a long tradition of setting albedo unreasonably high because they do not understand what albedo is. As a result, rendertimes are too high and renders look washed out (so people usually end up adding ambient occlusion or decreasing light bounces :D).I recently made again the mistake of reading up on corona on some other renderers' forums. It is always the same story - if a renderer offers an AO engine, then Corona results look "washed out and unrealistic, with no shadows in corners, probably blurred and faked as much as possible to make it render this fast"

If anyone was bored and wanted to watch something educative, we already started posting the videos online, but for now, they are in slovak language. They will be re-voiced fully in english after they are all complete, in early February. By that time, there should be around 20 videos and around 20 hours of free material.We create them and publish them after our Friday's classes at Uni are over, so far there are 2 basic modelling videos.[so disclaimer: might only hold value for total beginners right now, but eventually will go very complex, and until February only Slovak voice (Veronika and me, plus some of our modelers for SubD), in February English voice (again us) plus english subtitles ]Just wanted to put it up in case some slovaks/czech/people who don't care about voice would look it up.We'll supply full files for every stage by then too, right now, if someone wants the Cad files, just write me or maybe I'll post a link. It's just basic stuff Veronika drawn in AutoCad to simplify it.At the moment it's only HD1280px, but english version will come on my VimeoPro so it will show in its original fullHD quality.
Oh yes, moment, I'll ask Veronika where it is, and upload them when I find them on disk.
