Presto Engine (GPU+CPU)

Thea Presto is an advanced rendering engine that has been written from the ground up and is optimized for simultaneous GPU (NVIDIA & AMD) and CPU execution, maximizing your computing power. The engine has been tuned for fast, interactive rendering. This pushes GPU+CPU computing to the limits while keeping the high photorealistic quality of Thea Render.



In Thea Render, we have created a compact number of highly realistic materials using the most accurate physically based models. These models are designed to produce highly energy conservative material combinations.

The physically based material system has features such as an advanced layering system and a spectral color picker that are the heart of the render engine. These features allow realistic and convincing renders to be created.



A strong mathematical framework has been developed leading to a very robust, unbiased core. It can also be considered a light simulation tool, performing calculations in the full visible spectral space (380-780nm) including advanced phenomena like volumetric scattering and spectral index of refraction.



Thea Render v2.2 comes with a redesigned core engine and new features such as:

Beveled edges, Worley Noise & Edge Ramp procedurals, Triplanar Mapping, NVIDIA® OptiX™  6 integrations for RTX cards, support for LUT files and more…



Render times can be improved dramatically by having more computers contributing to rendering static images and animations. This is done transparently by installing and connecting our render node application to the main Thea Render integration. And even better, the render node application is free of charge, thus you can use all your spare machines to accelerate render results.
