HEAT Post-Penetration Effects Have Worsened; Fragmentation Barely Improved

I’m reporting critical issues with HEAT rounds’ post-penetration performance after the recent update—fragmentation feels less effective than advertised, and there are consistent bugs with damage delivery:

  1. No post-pen effects on moving vehicles
    When firing HEAT at moving targets, the round only registers as “penetrating armor” with zero post-pen damage (no fragmentation/overpressure). This mirrors the old bug where cannons failed to damage reversing vehicles: the round passes through armor without triggering any effect, even though it should detonate on impact.
  2. Worse performance on angled armor (even with clean penetrations)
    Post-pen effects degrade drastically on highly angled armor—sometimes even failing to damage crew despite a confirmed penetration. For example:
  • T114’s HEAT round penetrates the T-54’s upper glacis (angled), but deals no crew damage (no fragmentation/overpressure triggers).
  • Garage testing (static, angled armor) shows normal penetration + full post-pen effects (fragmentation/crew damage in the armor tester). In-mission hit analysis shows fragments spawning—but they deal 0 damage to crew.
  • Overpressure (which should trigger on HEAT detonation) has never activated in these cases, even when the round penetrates a tight crew compartment.

This discrepancy between garage tests and in-mission performance is consistent across multiple vehicles/HEAT types. The update claimed improved fragmentation, but in practice, HEAT’s post-pen reliability is worse than before.

Can the dev team investigate why in-mission movement/angle is breaking HEAT’s detonation logic?
