RapidMXS – aka Octopus plugin developer Miklós Gábor – has released UVReactor, a high-performance new UV unwrapping and UV packing plugin for 3ds Max. The add-on promises to unwrap and pack even multi-million-poly models in seconds and follows 3ds Max’s standard workflow and UI conventions. A high-performance UV unwrapping plugin for 3ds Max In development for five years, UVReactor is a high-performance automated UV unwrapping and UV packing plugin for 3ds Max.It’s CPU-based and runs in a single CPU thread, making use of the AVX2 instruction set to accelerate processing. Gábor pitches UVReactor as doing “eight times more work [in one CPU cycle] than most UV editors”, remaining “extremely responsive” even on multi-million-poly models. Follows familiar 3ds Max workflows Although the feature set is still relatively limited in the initial release, UVReactor features toolsets for unwrapping and packing UVs, and setting texel density.It works with 3ds Max’s native Graphite Modeling Tools, and follows standard 3ds Max workflows, using the same hotkeys as the viewport and native UV Editor. Other selling points include built-in UV cleanup, automatically resolving common UV artefacts, and the option to stitch multiple UV shells simultaneously. https://www.cgchannel.com/wp-content/uploads/2024/06/250415_UVReactor11_UVReactor12.mp4 A compilation of RapidMXS’s demos of the features added to UVReactor since the initial release, including Multi Object Mode, UDIM support, and workflow improvements from the 1.2 updates. Updated 15 April 2025: Since the original release of UVReactor, RapidMXS has steadily been putting out updates to the plugin, the latest being UVReactor 1.2.5. Below, we’ve rounded up the key changes to the plugin since its initial 1.0 release. The first major update, UVReactor 1.1, released just a month after version 1.0, added a new Multi Object Mode, making it possible to unwrap multiple objects or sub-objects simultaneously. UVReactor 1.1.3, released a month later, added support for UDIM workflows, making it possible to pack UV islands to separate UDIM tiles. UVReactor 1.2 released in March 2025, made UVReactor available as a modifier. That makes it possible to edit UVs anywhere in the modifier stack, letting you use UVReactor alongside the Edit Poly modifier, rather than just on Editable Poly objects. There have also been a lot of workflow improvements, including support for vertex and grid snapping, vertex pinning, non-uniform UV straightening, a circular selection mode, and new options for visualizing and selecting flipped polygons. The video embedded above compiles some of RapidMXS’s demos of the new features, and you can find complete changelogs for the 1.1.x and 1.2.x updates on RapidMXS’s Facebook profile.
