Interaction with some parts of complex model

[Ncit]

Hello everyone,
Is it possible to glow some parts of gltf model and add touchListener on it? Because I need to open dialog screens when user interacts with them, but did not find any solution for now

Hi!
Yes, detecting when a part of the model is tapped is supported in SceneView. However, the parts of the model should be highlighted either by changing a material or based on animations in glTF.

Is it possible to point me on functions, which used to detect tap? Also I did not get about materials, can you please explain what it is?

You can use this callback for all nodes: https://github.com/SceneView/sceneview-android/blob/848a95831d895a9c61143dc042195632f5505199/sceneview/src/main/java/io/github/sceneview/SceneView.kt#L310
Or set a callback for a particular node: https://github.com/SceneView/sceneview-android/blob/848a95831d895a9c61143dc042195632f5505199/sceneview/src/main/java/io/github/sceneview/node/Node.kt#L401
Speaking about materials, I mean that SceneView doesn't highlight the model parts on its own and you should find a way to do so.

Thanks, interaction works. But issue with that renderable id always changes((

However, if you find nodes by name in the model using Filament, you should be able to map the renderable ID to the node name.
