Is it possible make some parts of a model invisible? I want to create something similar to this (at 1:03). If you slide a plane over a model the part above the plane should be invisible so you can see inside the model.
Do you know any tips or where to find some help?

First, you will need create a minimap(Create a UI raw image and text render martial, set camera as the source of the textrenderer, assign the text render to the UI raw image) ;

Second, set the canvas in world space view.

Find some model and you can play with the model by moving the up down across the model, this part is fun and you should try yourself.

For your convenience and to learn, I upload a prototype to github and you can try my prototype.

The Clip function of Shaders may help you, as it can visually slice through meshes. Search for “clip()” in these examples.
