I have a quite long render, 8K@60fps and I’d like to stop the render and later resume from the last position.
The problem is that when resuming the render (so, next day I restart UE, load the render queue and set next frame batch), both Niagara particles systems and light functions will not get re-started from last “good” position and so there is no consistency between the last rendered frame and the new one. They basically get re-calculated from frame 0.
In Niagara systems I’m using the “deterministic” option enabled and a fixed seed, but that doesn’t seem to do the trick.
Any suggestion?
You would want to cache as much as possible in Sequencer. Thats the only thing that is really guaranteed. If you don’t want to do that you can use warmup frames to get your effect back to that frame but really caching in Sequencer is your best bet.
