is it possible for me to make an object disappear by making it move through a mesh. For an example. I have a car modeling, and i want it to disappear after the end of the road. I don't want the car to suddenly disappear like turning off the visibility or restrict rendering. I want the mesh to work like a mask for the car. So that when the car go through the mesh. It will vanish. I'm sorry i am bad at explaining. I hope the image can help me a little bit.enter image description here

  • $\begingroup$ yes of course, but you'll have to give the Boolean modifier to each object that is part of your car $\endgroup$

  • $\begingroup$ Do you need to see the newly cut faces / the inside of your car, as it disappears? Or do you plan on the angle being more or less as shown? $\endgroup$

You could use a Boolean modifier:

  • Create a cube. It will be the object that will make your car disappear.
  • In the Properties panel > Object > Display, choose Maximum Draw Type > Wire. In the Properties panel > Object > Cycles Settings > Ray Visibility, disable everything. Your cube is now transparent in both Object and Render mode.
  • Select your car, give it a Boolean modifier, choose Operation > Difference, and choose the cube as the Object.
  • Now when you move your car, the part that touches the cube becomes invisible.
