Short description of error
Eevee Image Texture Box mapping is inconsistent with Cycles output if object is scaled. The fact that it works but unreliably is even more dangerous than if it did not work at all.
Left is Eevee and right is Cycles:
Exact steps for others to reproduce the error
1, Open the attached blend file:
2, Switch right viewport to Rendered mode
3, Notice the difference in the result despite Eevee having support for Box mapping
Result: Eevee box mapping result is different if the object is scaled
Expected: Eevee box mapping result is identical to Cycles in all cases, even if the object is scaled.
