    Description

      When an opacityMap is added to PrincipledMaterial, the Model item is rendered incorrrectly. The same way it looks if alpha channel is added to base texture, even if the channel is completely white.

              PrincipledMaterial {
                  baseColorMap: Texture {
                      source: "maps/base.png"
                      tilingModeHorizontal: Texture.Repeat
                      tilingModeVertical: Texture.Repeat
                  }
                  opacityMap: Texture {
                      source: "maps/opacity.png"
                      tilingModeHorizontal: Texture.Repeat
                      tilingModeVertical: Texture.Repeat
                  }
              }
