Does dashed lines work the the line2 material. It seems to have parameters for dashed lines but it isn’t working for me. Any ideas?
```auto
import { LineMaterial } from "three/examples/jsm/lines/LineMaterial.js";
const lineMat = new LineMaterial({
color: 0x0000ff,
linewidth: 3,
dashed: true,
dashSize: 5,
gapSize: 5,
dashScale: 1,
});
lineMat.resolution.set(window.innerWidth, window.innerHeight);
```
Or have a look at the lines.js file in this codesandbox

Dashed lines only work if you call `Line2.computeLineDistances()` and if you enhance the line material by an additional define `lineMat.defines.USE_DASH = "";`. I know manually adding such code is hacky, but please read this [comment](https://github.com/mrdoob/three.js/blob/22ed6755399fa180ede84bf18ff6cea0ad66f6c0/examples/webgl_lines_fat.html#L236-L239) for more information.

Ok, fair enough. Thanks for your help!
