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.

WIll it work for a moving object? – Kidz Sep 02 '18 at 14:41

yes of course, but you'll have to give the Boolean modifier to each object that is part of your car – moonboots Sep 02 '18 at 14:46

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? – Robin Betts Sep 02 '18 at 16:35

I want the whole car to disappears as it going out of the camera. Btw i am doing a Isometric 3D modeling. – Kidz Sep 02 '18 at 16:57

The OSL route here might help, but it might be too complicated for what you need .. and/or the model might not be suitable. – Robin Betts Sep 02 '18 at 18:31

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.

Thanks a lot for the feedback. I will try to use the technique and make sure wether it will work or not. – Kidz Sep 03 '18 at 14:41
