# DMX Matrix

The DMX-Matrix feature creates a UV-mappable Matrix texture based on DMX values. This feature can be used to simulate thousands of LED fixtures without the performance overhead of individual fixtures because it directly reads DMX values from the internal buffer.

### Emissive

The DMX-Matrix is material based. To make it emissive *(visible in the dark)*, don't forget to raie the Emissive factor *(maximum value is 500%)*:

![Emissive material property](https://4198123652-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F-MhIYO0xEuDDA2b69m5L%2Fuploads%2F5Bgk0gcJll96UvkaNAJe%2Fimage.png?alt=media\&token=e424c4a5-8bf4-4a42-97df-59bf641901f1)

## DMX Matrix control

Now your material is ready to be used. You can patch the DMX Matrix fixture from the fixture library:

![DMX Matrix fixture](https://4198123652-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F-MhIYO0xEuDDA2b69m5L%2Fuploads%2FrMpZiCOEWHQaE0uM002W%2Fimage.png?alt=media\&token=385a7720-365a-43a8-ac5a-574eba5bb3a8)

The DMX Matrix fixture has the same mode as the DMX Matrix Texture, select the one you have set.

You need to patch as many DMX Matrix f*ixtures* as your DMX Matrix Texture has *(Columns x Rows)*&#x20;

Note: \
\- DMX Matrix fixture only controls 1 pixel at a time.\
\- Their position in world space is not important, they are not represented in 3D.

### Group DMX Matrix

To keep your project 3D Hierarchy as clean as possible, you can [group](https://help3.depence.com/depence-construction/depence-scene-graph-and-grouping/depence-group-objects) all your DMX Matrix fixtures:
