Yeh I was thinking about looking into moving the calculation to a worker thread in one method or another. The task concept is fairly interesting, that attempts to farm each calculation out to a separate thread right? Well a kinda queue of calculations to get through. Generally good for lots of small calculations, which would certainly cover the pathfinding system. Before I do that though i’m taking a look at a buried away A* method already included in the engine. Epic have said they used it for paragon with good results, so going to see if it can be adapted for my use, and if there’s any benefits to it.
