Modulare Toolset stands out in the superhive library because it pairs mesh precision tools with a strict UV grid system tuned for trim sheets, covering both the modeling and UV steps of a modular workflow.
Modulare Toolset is a Blender add-on aimed at modular level design and precision UV work. On the modeling side, Dynamic Central Split bisects any mesh by the exact center of its bounding box on X, Y or Z. The Smart Pivot System snaps an object origin to top, center or bottom with one click, and Quick Instance Array creates instances offset by exact mesh dimensions with zero gaps.
The UV side centers on a strict grid. The Strict Grid Generator unwraps into customizable grids from 1x1 to 16x16, while a Pixel Bleed Fix applies an automatic 0.2% scale reduction to prevent texture bleeding on trim sheets. UV Slot Navigation moves islands across grid slots with arrow buttons, Smart Stacking overlaps selected islands onto the active island, Snap Object to Target aligns mesh position and rotation to a target object, and UV Flip mirrors islands horizontally or vertically.
The add-on is compatible with Blender 5.0 and up as an extension, and works in 4.x. It is released under the GPL license. A demo video is available.
Modulare Toolset is best for environment and game artists building modular level design and trim-sheet UV layouts in Blender.
Modulare Toolset is completely free to download and use.
Modulare Toolset is compatible with Blender 5.0 and up, where it is ready to run as an extension, and it also works in Blender 4.x. The listing records Blender versions 5.0 to 5.1 for the add-on, and 4.x support is noted separately. If you are on a 4.x release, it should slot into that line as well. For the exact version you are running, check the developer's page before installing to confirm current compatibility.
Modulare Toolset handles texture bleed through its Pixel Bleed Fix, which applies an automatic 0.2% scale reduction to prevent texture bleeding on trim sheets. It sits alongside the Strict Grid Generator, which unwraps geometry into customizable grids from 1x1 to 16x16. UV Slot Navigation, Smart Stacking and UV Flip round out the grid tools, letting you move islands between slots, overlap selected islands and mirror them. For the full behaviour, the developer's page and demo video cover more.
Modulare Toolset's Strict Grid Generator unwraps meshes into customizable grids ranging from 1x1 up to 16x16. Version 1.1.3 also added a trim-sheet grid size of 32 at 4096x4096, along with auto size detection for trim sheets. Arrow-button UV Slot Navigation moves islands between grid slots, and Smart Stacking overlaps selected islands onto the active one. These grid options target the strict, repeatable UV layouts used in modular level design work inside Blender.
Modulare Toolset is listed as free within this catalog, and it is released under the GPL license. It is also marked as Blender extension compatible and as a Dev Fund contributor. Licensing and availability can differ on the developer's own page, so check there for the current terms before you download. Confirm the latest details directly with the developer for the specific version you plan to install, since specifics can change between releases.
