With the release of unified lighting, the forcefield material no longer has that outline effect whenever it intersects with other objects. This mainly happens when LightingStyle is set to Soft. When set to Realistic, the effect is restored, although not entirely as the effect should be visible inside the object as well. PrioritizeLightingQuality has no effect.
This is my first bug report, so let me know if I am missing something
Recreating the same scene, the effect is entirely missing, only showing a faint wall. I am using LightingStyle Soft and PrioritizeLightingQuality enabled here.
The effect does appear in realistic like as before, which makes this issue fixed for both LightingStyles.
The issue with the outlines being missing inside the object is still present, and to better showcase this, here is a screenshot with 3 cubes, each being different.
The left is a normal part, the middle is a meshpart cube with the faces inverted, and the right is both being overlapped to show the intended behavior.
