The saga continues! The problem basically is that a certain flag for effects, which forces it to get rendered just before the view model and out of the leaf system ( FLAGS_DRAW_BEFORE_VIEW_MODEL ), is not working properly.
There's a function CParticleMgr::DrawBeforeViewModelEffects that is not called at all in my pipeline. I see it's called from ViewDrawScene_Intro which calls DrawWorldAndEntities, but my pipeline passes through the function WaterDrawWorldAndEntities where this thing is not called. Did I break the pipeline somewhere or is it a bug? I can add the function somewhere in my pipeline, and then my muzzle flashes work properly, but they still get rendered in the main loop when it's not culled which triggers an assert. I can fix that easily, just wondering where it or I went wrong & what caused the bug in the first place. -- Maarten > Just a quick update, to maybe still ring a bell somewhere: apparently my > muzzle flash for my view model has a bounding box that is being tested > against world geometry, if I turn on the debug I clearly see the muzzle > flash disappearing the moment the bounding box is completely in the world > geometry somewhere ( floors, walls, ceilings ).
