Question Partially Render a model

Hi, i am very new to Unity and graphics in general.

I need to render a model and be able to "slice" it in real time.
For example i need to see the front 80% of the model (rest should be invisible) and than change it so i can see more or less of the model. And i need to see edge between the visible and the invisible part.

I already tried something with DepthMasks, but that just makes everthing behind it invisible, so not exactly what i need.

I thought about editing the mesh in real time, but i dont think that is possible with a complex model.

Any help is appreciated.

 

The term you'll want to search for is "cross section shader".

 

thank you, thats exactly what i need!
