## About this Block

**What it does:** The **Simplify Mesh by Amount** block simplifies an input mesh by removing elements of the mesh, until a specified percentage of triangles have been removed. The Amount input must be a number greater than 0 and less than 1. An input of 0.3 reduces the face count of the mesh by 30%.

**Common uses:**

* Reducing the face count and file size for export

**Tips:**

* The decimation algorithm does not take into account a surface tolerance (the distance between any original input mesh surface and the simplified new surface).
* To simplify a mesh while maintaining a specified surface tolerance, use the Simplify Mesh by Threshold block.

Simplifies a Mesh by a specified target percentage, represented as a value from 0 to 1. An input of 0.1 will remove approximately 10 percent of the faces. A value of 1 will attempt to remove as many faces as possible, while still trying to preserve the general shape of the Mesh.

### Inputs

| Name | Type | Description |
| - | - | - |
| Mesh | [Mesh](../../../../block-documentation/types/mesh) | Mesh to simplify. |
| Amount | [Scalar](../../../../block-documentation/types/scalar) | Target percentage for simplification represented as a value between 0 and 1. A value of 1 will attempt to remove as many faces as possible, while still trying to preserve the general shape of the Mesh. |

### Outputs
