### Remarks

This attribute is optional. You can use it to describe additional texture coordinates.

UV coordinates are commonly represented using the [Vector2](/engine/6000.6/script-reference/unityengine/vector2.md) format, which consists of two 32-bit floating-point values, resulting in 8 bytes per vertex. If [vertex compression](/engine/6000.6/manual/analysis/graphics-performance-profiling/compressing-mesh-data-optimization/configure-vertex-compression.md) is applied to this attribute, each component is compressed to 16-bit floating-point values, reducing the total to 4 bytes per vertex.

This attribute corresponds to the `TEXCOORD7` semantic in the HLSL shading language.

You can access vertex UVs using methods such as [Mesh.GetUVs](/engine/6000.6/script-reference/unityengine/mesh/getuvs.md) and [Mesh.SetUVs](/engine/6000.6/script-reference/unityengine/mesh/setuvs.md).
