Animate Color in Simulink 3D Animation

Hi, I'm creating Robotic car painting station (Animation/Simulation), and I need to animate color change of car's body, but I can't check 'Color' node from VRML tree in VR Sink's parameters. Is it somehow possible to do that?

Thanks for answers.

Hi Tom, just came across the answer to this myself!

By default Simulink 3D cannot access a property without a name, which happens when you add a material. Simply open up the .wrl file and navigate to your shape:

appearance Appearance { material Material { }}

Noticing the material is currently empty, and without a name. Do the following to fix this:

appearance Appearance { material DEF LiqMat Material { }}

Where I have added a name LiqMat using DEF.

Best of luck!

It works! Thanks!

Note you can also change the name of a material within VRealm or Simulink's 3D Editor, in a similar way you can change transform names (click and wait).

Sorry but for me does't work. Can you please tell me the error in my world? since I still can not select the box for the color because instead I have a black "x". I need to change the color of the last element "ContactForce" to see when is stick and when is slip. Thank you
