3d-io GmbH

3d-io GmbH is a small German studio that has spent more than two decades building plug-ins and middleware for 3-D artists rather than end-user applications, so its catalogue is narrow but deep. The company’s best-known tool, Exr-IO, is an Adobe Photoshop plug-in that lets compositors, texture painters and matte artists read, write and layer multi-channel OpenEXR frames without flattening or data loss. Because EXR is the de-facto standard for high-dynamic-range render passes from 3-D packages such as Blender, Maya, Cinema 4D and Houdini, the plug-in is used wherever beauty, depth, normal, velocity or cryptomatte passes need to be inspected, graded or re-combined in Photoshop. Typical workflows include assembling CG over live-action plates, packing utility AOVs into a single file for hand-retouching, or round-tripping 32-bit float images back to the 3-D department for look-dev approval. Beyond Photoshop, 3d-io’s code also ships embedded in commercial renderers and broadcast pipelines that require rock-solid EXR compliance, and the developer is active in the OpenEXR working group, so new compression options, deep-pixel support and alpha-channel conventions are implemented almost as soon as the format is updated. All of the publisher’s software is available free of charge on get.nero.com, where downloads are delivered through trusted Windows package sources such as winget, always install the latest release, and can be queued for batch deployment alongside other applications.
