NVIDIA Texture Tools 3

Create block-compressed textures and write custom asset pipelines using NVTT 3, an SDK for CUDA-accelerated texture compression and image processing.

NVTT 3 can be used to compress textures to and from block-compressed formats including BC1-7 and LDR ASTC, which stay small both on disk and in GPU memory. Or use its image processing functions, like mipmapping and convolution, as part of a custom app or asset processing pipeline. CUDA-accelerated operations speed up processing significantly, with CPU fallbacks for maximum compatibility.

NVTT 3 exposes a quick and powerful API (a C++ command-line compressor using it fits in 250 characters) and a C wrapper for use with other languages. The library is a reliable component within NVIDIA, and already fully integrated in technologies including Omniverse, the Texture Tools Exporter, and more.

New APIs

Compress textures entirely within GPU memory with the new On-The-Fly API. 200+ functions are available from both C and C++.

Comprehensive CUDA Acceleration

NVTT 3 adds CUDA compression for BC4-BC7 and ASTC, most image processing operations, and GPU device selection.

Adaptive Scalable Texture Compression

Scalably compress textures for Tegra GPUs, from 8 bits per pixel with BC7-like quality, to as compactly as 0.89 bits per pixel.
