What is PVRTexTool?#
PVRTexTool is a utility for compressing texture assets, an important technique that reduces the memory footprint of the asset both on disk and in RAM, as well as reducing the GPU memory bandwidth required to sample compressed assets. Please see the PowerVR Performance Recommendations for more information. PVRTexTool can transcode to a variety of widely-used compressed texture formats; additionally, all core texture formats for OpenGL (and ES), Vulkan, and DirectX are also supported.
PVRTexTool also includes a number of additional features that can be used to pre-process the image data, such as:
Normal map generation
Pre-multiplying RGB by alpha
PVRTexTool is comprised of several distinct components:
PVRTexTool Graphical User Interface (GUI) - allows manipulation of texture data in an interactive graphical environment with immediate visual feedback.
PVRTexTool Command Line Interface (CLI) - allows easy batching of texture conversion and compression operations via calls from a script or batch file. Only the executable is needed.
PVRTexTool Plugins - allows various popular software applications access to PVRTexTool functionality. Plugins are available for Autodesk 3ds Max and Autodesk Maya.
PVRTexTool Library - allows easy integration with existing tool chains, via a simple C API and library for accessing PVRTexTool functionality.
The GUI, CLI, and library components are all available for Windows, Linux, and macOS.
For best compatibility, it is recommended that PVRTexTool is installed on machines running at least Windows 7, macOS 10.11 (El Capitan), or Ubuntu 16.04.
