UE 4.7 lists the following additions to the Physics engine;
- New: Added the ability to register per sub-step simulation callbacks for
more accurate application of custom
forces.
How do I access these through Blueprints?
Upon further investigation it seems like running Blueprints in the physics thread isn’t possible (as of 4.8).
All Blueprints run in the main thread (i.e. once per rendered frame?), although you can make them tick before or after physics by creating a new C++ class and modifying its tick group.
Has this been changed since 4.22? Is there still no way to access the substep within Blueprint? Can’t find anything.
