Texel Density

How many texture pixels cover one meter of surface, the key to evenly sharp textures.

Texel density is the ratio of texture resolution to surface size, usually given in pixels per meter. If one prop has four times the density of its neighbour, it looks crisp next to a blurry one, even when both textures count as "high resolution". Density depends on the texture size, the object's size and how much of the UV space its surfaces occupy: a 2048 px texture stretched across a 2 m wall gives about 1,024 px per meter. On Grab3D, High Detail models use 4K textures (1K in the lighter variant), most Lightweight models use 2K, and the low poly models use a tiny palette texture where density hardly matters. Because every model is built in real-world meters, large buildings end up with a lower density than small props. Plan tiling materials or decals if the camera gets close.
