Earns its place in the superhive library as a compact, single-file addon that pairs HSV color adjustments with practical material utilities, including a one-click Megascan fix, all reachable from one side-panel tab.
HSV Color Correction Tools is a Blender addon from SMArchviz for adjusting the color tones of a scene. It lets you tune texture hue, saturation and brightness, and add a color overlay to match a scene's tone. The developer built it for quick, easy access to these adjustments while working on scenes.
Beyond color tuning, the addon bundles several material utilities. A one-click Megascan materials fix corrects the Megascan asset material on an object imported with the Megascan addon in Blender. A Clone Material tool duplicates the material on a selected object, Arrange Material Nodes organizes a selected object's nodes in the shader editor, and a Mapping UV Node option adds a mapping node and lets you adjust its values.
The tools live under an HSV tab in the side panel after you install the Python file through Blender's preferences. It works across Blender versions from 3.4 through 4.4 and is released under the GPL license. The 1.1 update brought bug fixes and UI improvements, and a demo video is available.
Hsv Color Correction Tools is best for blender users who want quick hue, saturation and brightness adjustments along with material tools like Megascan fixes and node arrangement.
Hsv Color Correction Tools is completely free to download and use.
HSV Color Correction Tools lists support for Blender 4.4, 4.3, 4.2, 4.1, 4.0, 3.6, 3.5 and 3.4, so it covers a broad range of releases from Blender 3.4 up to 4.4. The addon installs through Blender's preferences as a Python file and appears as a dedicated HSV tab in the side panel, where its tools become available. If you run a version outside this range, check the developer's page before installing to confirm the addon behaves as expected on your setup.
HSV Color Correction Tools installs from Blender's preferences. Open Edit > Preferences, choose Install and select the HSV_Addon_Vx.py file, then activate it. Once enabled, a tab named HSV appears in the side panel, and all of the tools become available from there. The addon is distributed as a single Python file. A demo video is available if you want a look before installing, and documentation is listed among the addon's resources, so you can reference the steps and tools once it is set up.
HSV Color Correction Tools includes a Megascan materials fix that, with one click, corrects the Megascan asset material on an object brought in through the Megascan addon in Blender, which otherwise comes with issues that had to be fixed manually for each one. Alongside that, the addon offers a Clone Material tool for duplicating the material on a selected object, an Arrange Material Nodes tool for organizing that object's nodes in the shader editor, and a Mapping UV Node option for adding a mapping node and adjusting its values.
HSV Color Correction Tools is listed as free here, and it is released under the GPL license. Because pricing and licensing can change over time, check the developer's page for the current terms before you rely on any particular arrangement. The GPL license covers how the addon's code can be used and shared, which is worth reviewing if you plan to modify or redistribute it. For everyday use inside Blender, install the addon through preferences and work with its tools from the HSV side-panel tab.
