Thea Render v2.1

In Thea Render, we introduced innovative techniques and algorithmic optimizations to achieve superior performance. All possible paths of lighting transfer are explored, delivering the highest accuracy.

The material system with Physically Based material primitives and Advanced Layering System is at the heart of the render engine. These features lead to the most realistic and convincing renders.

Presto is great fun to work with, especially since you can get immediate feedback with production quality due to its fast, interactive response.

Participating media and Sub-Surface Scattering are resolved with full accuracy utilizing our optimized volumetric scattering techniques.

Systems with multiple GPUs can use the Split Frame option to vertically divide the rendered image into as many parts as there are devices on the machine, for faster interactive refresh rate.

Two new Tone Mapping operators have been added in Thea Render. Filmic allows the user to have complete control over Highlights and Shadows while Reinhard provides a robust way to automatically compress high dynamic range renders.

The user can stop a rendering and resume later without losing any progress. This is ideal when resources are limited or render job needs to be transfered to other workstations.

Triplanar is a special mapping technique similar to Cubic Mapping with the addition of blending together the projections from each axis (x, y, z). Triplanar Mapping along with the Cut-Off and Sharpness parameters can be used to eliminate the seams of a texture without the need of proper UV Coordinates.

The Edge Ramp procedural makes it possible to apply color to the edges of a surface based on the minimum angle of adjacent faces and the radius of the edges.

Thea Render supports Cuda 10 making it possible to use High-End GPUs like Titan-V and RTX.

A strong mathematical framework that has led to a very robust unbiased core. It can be also considered as a light simulation tool, performing calculations in the full visible spectral space and including advanced phenomena like volumetric scattering and spectral dispersion.

One of the great advantages of using the unbiased core is that no effort is needed to set up the engine. Realistic results are produced without any artifacts. This way, the artist and designer can focus exclusively on bringing their ideas to life, without fiddling with any engine parameters.

Millions of instanced polygons can be rendered without an issue due to our geometric compression techniques. And even if scene cannot fit in GPU, Presto can still run entirely on the CPU.

There are two denoising methods to choose from. NVIDIA® OptiX™ delivers fast unsurpassed denoised renders. And in case that NVIDIA GPU graphic card is not available our built-in denoiser can still be used to accelerate production rendering.

Custom Material and Light Evaluation allows the user to select which components (such as Diffuse, Translucent, Reflectance, Transmittance, and SSS) will be evaluated for a given material and light, thus removing unwanted contributions and accelerating render times.

A separate material can be assigned to the back face of a surface. This is very useful for models without thickness like labels, leaves, etc.

Beveled Edges can be used to smooth out the edges of an object with controls over the radius of the effect and the minimum angle of the adjacent faces.

LUT stands for Look-up Table and the files can be used to change the overall color and tone of an image.

The Worley noise procedural is able to create cell-like structures that simulate textures of water and stone among others.

Support for AMD Graphic Cards rendering has been added through OpenCL. Please note that this feature is Windows only and under continuous improvements.
