I am working on a project where I need to show and animate terrain contours. Unfortunately my model is too big to be able to use boolean modifier with array of planes.
The attached gif shows what I am after it has a couple of limitations.
1.I did it using boolean and freestyle render
2. I had to render free style lines separately as there were artefacts when I tried to render together with terrain mesh
I have tried creating a shader and compositing nodes (using one of the tutorials) but it is not precise and no way to control contours offset.
Is there any other way? To achieve realtime contours on a huge mesh?
