Versions:
3d-io Exr-IO 2.06.00 is a free plug-in that equips Adobe Photoshop with an extensive, bit-exact OpenEXR import and export pipeline, targeted at compositors, texture artists, matte painters, and VFX supervisors who need to move high-dynamic-range imagery between 3-D renders and 2-D finishing. Once installed, the add-on appears inside Photoshop’s Open and Save dialogs, letting users read every channel stored in an EXR file—RGB, depth, motion vectors, cryptomatte, ambient occlusion, specular, emission, normals, alpha, and custom arbitrary channels—into an automatically generated layer stack with correct naming, bit depth, and linear gamma, eliminating the manual split-and-rebuild workflow that standard Photoshop lacks. Conversely, the exporter can write multilayer EXR files back from the assembled comp, preserving all layers, transparency, and floating-point fidelity for downstream 3-D or compositing packages. The extension supports the complete current OpenEXR specification, including deep pixels, multi-part files, PIZ/PICT/ZIP compression, and 32-bit float, 16-bit half, and 32-bit unsigned integer pixel types, ensuring compatibility with renderers such as Autodesk Arnold, Chaos V-Ray, Maxon Redshift, and Foundry Katana. Typical use cases include importing rendered beauty passes for shot-finishing, extracting utility AOVs for selective color grading, round-tripping texture paint work to game engines, and assembling multi-channel UV masks for look-dev tweaks. Because the tool is purpose-built for Photoshop, it integrates natively without altering the host’s color management or requiring intermediate conversion utilities. Only one version, 2.06.00, is currently offered. The software is available for free on get.nero.com, with downloads provided via trusted Windows package sources such as winget, always delivering the latest version and supporting batch installation of multiple applications.
