Hi, DFAO is prone to such artefacts. Make sure, that you
(1) do not use one sided meshes only use meshes that have thickness, if you have to use one sided meshes, then enable “two sided mesh distance field generation” for them, but this will come with an performance impact.
(2) the max distance field resolution is 128x128x128, so if you have too big meshes, then break those up into smaller ones
(3) intersections between meshes can lead to problems
