<div dir="ltr">Hey Brecht,<div><br></div><div style>I know you've been working on an ubershader to be available in an upcoming release, and I wanted to toss in my two cents as far as the feature set goes.</div><div style>
<br></div><div style>I recently released an ubershader created entirely with the node group system to the community, and the response has been overwhelmingly positive so far. It's given me a good reference for what people seem to really enjoy in terms of added functionality.</div>
<div style><br></div><div style>The shader has the standard Diffuse/Glossy/Anisotropic/Transparent options, as well as options for SSS, the choice between decoupled Refraction/Glossy for glass-like materials or the glass shader itself, emission, and a flat color matte that only affects camera rays.</div>
<div style><br></div><div style>There are a couple of options in the glass/refraction shaders that people have absolutely gone nuts for. There is the option built in to control shadow color, allowing for tweaking opacity for things like flat glass tables without having to mix several nodes together. On top of that, there is an option for fake, nearly free caustics using some vector math and the normal and incoming geometry variables. This seems to be the one feature that people love most from the shader, and it's surprisingly convincing, especially for animations. </div>
<div style><br></div><div style>The other feature people really seem to like is a simplified Beer's Law transmission/absorption effect for glass/refractions. It includes the option to manually control the transmission color and depth at which it occurs.</div>
<div style><br></div><div style>If you'd like to take a look at the shader the download link and full documentation are over at <a href="http://www.blenderartists.org/forum/showthread.php?283248-Ubershader-v4-0-New-Release-5-24-2013-Come-and-Get-It!">http://www.blenderartists.org/forum/showthread.php?283248-Ubershader-v4-0-New-Release-5-24-2013-Come-and-Get-It!</a></div>
<div style><br></div><div style>As always, many thanks for the work you do for the Blender and the community as a whole. I hope I can be of some help in the decision making process.</div><div style><br></div><div style>Matt Heimlich</div>
