Projectcheck earns its place in the superhive library for consolidating a long list of geometry and UV checks into a single Blender panel, with support spanning Blender 2.8 through 4.2 under a GPL license.
Projectcheck is a VFX Grace add-on that pre-flights models in Blender and displays special model details intuitively, helping users assess the quality of their models. It runs checks for a broad set of issues, including isolated points, edge vertices, doubles, boundaries, n-gons, intersected faces, overlapping polygons, non-plane geometry, overlapping UV vertices, overflowing UV, UV proportion, normal direction, missing textures, degenerate polygons, 6+ edge poles and non-manifold geometry.
Results appear in a table, and clicking an entry redirects you to the model's location and switches to editing it. A 'Clean' action clears unused nodes, an 'All' toggle checks every object or only the selected ones, and 'Pin' keeps the windows on top. The add-on can also show the elapsed processing time and sort results.
For large projects, checking only some items or objects is recommended to avoid Blender crashing during processing. Projectcheck installs through Blender's Preferences via Add-ons and is released under the GPL license.
Blender Addon | Projectcheck is best for pre-flighting Blender models and assessing their geometry and UV quality.
Blender Addon | Projectcheck is completely free to download and use.
Projectcheck supports a wide span of Blender releases. On Windows it runs on Blender 2.80 through 4.2, covering the 2.8x, 2.9x, 3.x and 4.x series. On Linux it covers Blender 2.80, 2.81a, 2.82, 2.82a, 2.83, 2.90, 2.93 and 3.0 through 3.4. If you work across several Blender versions, confirm that your specific build appears in the supported list on the developer's page before relying on the add-on.
Projectcheck installs like a standard Blender add-on. Open Preferences, go to the Add-ons section, choose Install, then locate the add-on file to install it. Once enabled, you run it from its start window. If processing feels slow, you can uncheck some of the checking items selectively, and for very large projects it's recommended to check only partial items or partial objects to avoid Blender crashing during processing.
Projectcheck is listed as free here in the catalog, and it is released under the GPL license. Licensing terms can change over time, so for current pricing and any purchase details, check VFX Grace's own product page. For reference on updates, the changelog notes version 1.4 added support for Blender 3.1, while an earlier release added elapsed-time display and a sorting function alongside several bug fixes.
Projectcheck presents its findings in a table, and clicking on the data for an object automatically redirects you to that model's location and switches to editing it, so you can work on the flagged geometry directly. Alongside this, the 'Clean' action removes unused nodes, the 'All' toggle switches between checking every object and only the selected ones, and 'Pin' keeps the add-on windows on top while you work.
