It is possible to achieve a "section cut" "clipping plane" shader as shown below - solved on this thread on the bA forums.
However, it doesn't quite solve the ability to create a cap. When two section planes are applied, it is quite obvious that it is just showing the backface and not a true cut.
I am looking for two potential ways to mitigate this issue:
- Try to improve this shader such that a cap is shown in the simplest way possible for Eevee.
- Modify the shader such that a thick line can be shown where the cut is made, to help visualise the cut position, similar to how SketchUp does it:
Really really appreciate if somebody can crack this - I've tried without success!
