Stands out in the Blender Extensions library for consolidating texel density tasks, calculating, rescaling, copying and visualizing, behind a select-and-click workflow.
Texel Density Checker is an add-on by IvanVostrikov for working with texel density in Blender. It calculates texel density for a mesh across different texture sizes, including non-squared and custom sizes, and can rescale UVs to reach a target density. You can also copy texel density from one object to others and select faces that share the same density or UV space.
Using it is straightforward: select your mesh or faces, set a texture size and click a button. For inspection, it can visualize texel density, UVs and islands using a checker material and vertex color. Recent versions add presets for small texture sizes and custom checker image assignment. Note that the Blender Extensions build ships without a C++ calculation backend.
Released under the GNU General Public License v3.0 or later, the extension is compatible with Blender 4.2 LTS and newer and requires no special permissions. On the Blender Extensions library it has over 89,000 downloads and a 5.0 rating from 45 reviews.
Texel Density Checker is best for blender artists checking, matching and rescaling texel density across UVs, and visualizing UVs and islands.
Texel Density Checker is completely free to download and use.
Texel Density Checker lists compatibility with Blender 4.2 LTS and newer, so current Blender releases are supported. You can add it by dragging and dropping the extension into Blender, or by downloading and installing it from disk. The add-on requires no special permissions to run. Once installed, you select your mesh or faces, pick a texture size and click a button to calculate texel density, rescale UVs toward a target, copy density between objects, or visualize the results with a checker material and vertex color.
Texel Density Checker's Blender Extensions version has no C++ backend. The toolset still calculates texel density for meshes at different texture sizes, including non-squared and custom sizes, rescales UVs toward a target density, copies density from one object to others, and selects faces sharing the same density or UV space. The workflow stays the same: select the mesh or faces, choose a texture size and click the button to run the operation.
Texel Density Checker installs either by dragging and dropping the extension directly into Blender, or by downloading the file and installing it from disk. It requires no special permissions. After installation you work by selecting a mesh or faces and a texture size, then clicking a button. The add-on covers calculating texel density, rescaling UVs to a target, copying density between objects, selecting faces by matching density or UV space, and visualizing density, UVs and islands with a checker material and vertex color.
Texel Density Checker is released under the GNU General Public License v3.0 or later. In this catalog it is listed as free; for current licensing and any sponsorship options, check the developer's page. The extension requires no special permissions and is compatible with Blender 4.2 LTS and newer. Development can be supported through the developer's listed channels, though that is optional and separate from installing and using the add-on.
