With this function you can subtract a part of a model by using another, this is an example of what exactly it does:
As you can see, the cylinder model has deleted a part of the mountain and a part of the grey box...
Let's start the tutorial.
We'll create a volcano (a bit simply ) from a cone.
Start 3D Studio Max (I use version 7) and create a cone.
If you want you can use my data:
Now we'll use the Oiltank ( ), so, go to Extended Primiteves and select OilTank.
Make this object in the middle of the cone, using the Top View
As you can se inside the Step 2 image, the "Oiltank" is at the bottom of scene, so you must move it up.
This is the active part.
Select the cone object, go to "Compound Objects" and select Boolean.
It's time to apply the effect to the model.
Make sure "Subtraction (A-B)" is selected and press "Pick Operand B".
Now press H on keyboard and select the Oiltank.
Press "Pick" to apply the effect.
This is the best step: Enjoy!
Well, this model isn't nice, but this is a tutorial.
I hope you like it.
