AMD TressFX 4.1 released
« on: January 27, 2020, 05:52:10 PM »
We are delighted to announce our TressFX 4.1/Unreal® Engine integration and our TressFX 4.1/Radeon™ Cauldron framework implementation. The TressFX library is AMD’s hair/fur rendering and simulation technology. TressFX is designed to use the GPU to simulate and render high quality realistic hair and fur.

This latest version – TressFX 4.1 – is designed to be a performance and feature enhancement of TressFX 4.0. Highlights include further optimization of the physics simulation shaders, new rendering features, documentation and tutorials, and an updated TressFX Exporter for Autodesk® Maya®.

This release also demonstrates TressFX integration with Unreal Engine (4.22). This is a minimal integration to improve ease-of-use with multiple TressFX components, features, and rendering and simulation materials.  Developers wishing to further the integration or customize it for their own requirements may find this basic level of integration a helpful first step in that process.

TressFX/Radeon™ Cauldron demonstrates how TressFX can be cleanly dropped into an existing codebase.
