Unable to change element colour in Viewer
问题 To test out a PoC, I'm trying to colour a selected element red. To do this I have created a class, as below, but nothing happens to the elements when I select them. I've tried a number of the examples around the web (including some which create a mesh proxy for the render proxy and add an overlay) but nothing works. How do I change the colour for a given element (either dbId or fragId )? I can't find API documentation for most of this in the Forge API, so I'm flying a little blind. /* global
