I have this strip on my landscape that I want to make disappear from where the digger currently is, and then following the digger towards the end of the strip, to reveal the trench underneath.
What is a good way to do this? Can I animate an object that removes the ground strip? The camera is static in this scene so I could also imagine using a mask, or doing something in the video sequence editor.
*Cutting out my strip (knife project) messes up the connection with the rest of the landscape (they both have displacement maps). So I think I need to keep both images and animate a mask in the video sequence editor or something.
