is that the latest build, default animation settings? If yes, then I would like to take a look at the scene (can you create a bug report)?
Bug report on mantis. I might have actually found the reason: flickering happend where a decal was placed nearby. I alligned the decals with the position of the walls and pushed their postition one tick away from the wall. Even though they are infront, they still flicker in the viewport, but do not in the on the final render. Maybe the GI calc has Z-depth issues? (Embree precision and high quality were on, I didnt play with it back then)
build was 13.01.15
I made periodic saves, so this is the file that was used back then.
it's actually 7k objects, with 10gb textures with the .max file being 160mb and taking 15minutes to open on a 4.6ghz 8350 ;]
I deleted everything, that was hidden during the render. Now it opens in almost instantly ;_;
No textures, obviously.
Settings were default, expect max ray intensity 4.0, light samples multiplier 4.0; the precalculation of UHD cache were done with 30 precomp. Amount (stopped at 200k anyways) and 4096 record quality. There were two caches, one for each room. Saved out and rendered the 150 frames with one and the rest with the other .hdc. Precomp was calculated by placing the camera in a corner and making it wideangle, so it covers all of the room.
https://corona-renderer.com/bugs/view.php?id=731edit: when I switched to dailies there was a VERY strange bug. The first time I saved after the switch, two Spotlights kept reseting their fallof values, each time I reloaded the scene O.o Brain-Computer fart I suppose...
