CZML Polyline Material Property: Image - Image Material

CesiumJS

I am interested in seeing how the Image Material looks on polylines, I’ve used several test images and had nothing but white texture show up no matter the settings I use. Here’s what i’ve been using in the czml:

{
    "id":"/object/Link_point1_to_point2",
    "polyline":{
      "show":[
        {
          "interval":"2021-08-09T19:00:00Z/9999-12-31T23:59:59.9999999Z",
          "boolean":true
        }
      ],
      "width":10,
      "material":{
        "imageMaterial":{
          "image":{
            "repeat": [1,1],
            "uri":[
              {
                "interval":"2021-08-09T19:00:00Z/9999-12-31T23:59:59.9999999Z",
                "uri": "../waveformline.png"
              }
            ]
        }
      }
    },
      "followSurface":false,

      "positions":{
        "cartographicDegrees": [-75, 39, 250000, -76, 39, 250000]
      }
    }
  },```


I looked at the network tab of the window and saw that "waveformline.png" was never loaded on open, so I'm guessing my code is not set up correctly.

I'm interested to see what capabilities I could make with transparent images for my polylines so I would hate to have to abandon it before getting to check out some neat opportunities!

I have since found the correct code after more digging.

  "material":{
        "image":{
          "transparent": "false",
          "image":{ "uri": "../gradient1.jpg" },
            "repeat": {
              "cartesian2":[1,1]
            }
        }
      },

This is the proper image material code to put in the czml file to use image as polyline texture. Cheers
