About the Mesh polygon reducer
Reducing, or decimating, a mesh removes triangles while keeping the overall shape, which lowers memory use and draw cost and is how level-of-detail (LOD) versions of a model are made. This reducer targets a percentage of the original triangles and keeps UVs, materials and animations intact.
How to use the Mesh polygon reducer
- Drop a GLB, glTF or OBJ model.
- Pick a target percentage of the original triangle count.
- Compare the original and reduced mesh in wireframe.
- Download the reduced model as a GLB.
Frequently asked questions
Drop a GLB, glTF or OBJ model, choose the percentage of triangles to keep, and download the simplified model as a GLB. The reducer preserves UVs, materials and animations.
Decimation is the process of collapsing edges and removing triangles from a mesh while keeping its silhouette as close as possible to the original, producing a lighter model or an LOD.
Yes. The reducer keeps UV coordinates, material assignments and animations, so the lighter model still textures and animates.
No. The reduction runs in your browser and the model is not sent to a server.
