I have an issue which I've discussed extensively with the developers of Flashback. I have a recording of a large structure that I am using DH to render in full without murdering my computer. Overall the quality of the scene is quite good however I am struggling to get the structure to render properly in Flashbacks output. The problem seems to be that either distant horizons or iris/shaders or a combination of the two are not implementing flawless frames properly. Meaning flashback isn't being told when the frame is finished rendering before saving it and moving on to the next frame. This results in the transition from blocks within render distance of the camera to LODs occurring causing artifacts in the final render.
