New in This Version

Fresnel Ramp Procedural
The Fresnel Ramp procedural gives a great flexibility controlling a varying reflectance with respect to the viewing angle. It is intended to replace our Fresnel curve parametrization for coating and glossy materials, as a more powerful means to achieving a natural look for a broad range of materials (and especially for cloth, such as satin and velvet).
Improved Shadow Catcher
In the new edition, the shadow catcher has been substantially improved. The shadows coming from image-based lighting look much more natural now, following image highlights. The sun shadows can also be integrated along with the environment reflections that make the new shadow catcher infinitely more realistic.
Substance Material Converter
Our brand new Substance to Thea converter takes advantage of the Allegorithmic high quality applications and huge material database, to convert out-of-the-box to Thea Render materials. All Substance applications are supported (Painter, Designer, Bitmap2Material) along with all metallic/roughness physically-based materials.
Colored Coating Absorption
The ultra realism is at the fine details. And colored coating absorption is such a detail that can be seen in real-life materials, like metallic car paints and tinted wood varnish, where a color shift can be seen at shallow angle. This absorption can now be described easily by providing the resulting absorption color at a nominal penetration distance.
Section Cuts
Section cuts are defined as planes that cut out part of the scene. The idea is that, without breaking your current model, clipping planes can be defined giving the possibility to take a "look inside". The geometry is not actually removed but it is still there, contributing to reflections and secondary bounces; this way the lighting is not altered.
Online Material Repository
With all the material advances of the new edition, there is nothing better than having an open material repository where all users can interact, upload and download materials. We are proud to present our online repository where all official materials can now be found, along with user own creations.
