hi guys, need help again here

still with my car-modification project for college

can i apply a specific name for a part in my 3D car model
and then in director hide & unhide that part with a script?

for exmple :

the car had a wing spoiler in the model
in director there's a button that when pressed can make those spoiler appear or disappear ..

anyone could help me with the script pleaasee :'(

Find yourself a copy of the 3DPI so that you can examine your scene.

You can make your spoiler into a group if it's not a single model. Then you would use addToWorld/removeFromWorld or similar to show/hide it.

You can also make geometry that uses a specific shader disappear / reappear by adjusting the blend (opaqueness):

  --enable transparency
  member("3dworld").shader("wing spoiler").transparent = true
  --make 100% tranparent
  member("3dworld").shader("wing spoiler").blend = 0

Also, you can use the visibility property of the model to prevent rendering:

member("3dworld").model("wing mirror").visibility = #none
