Hello. I recently have been trying to make a cinematic for a map, but chunks or (even smaller parts) keep acting very strangely, and it's completely unpleasant.
When I fly around (in ReplayViewer) I can easily load areas, but once I preview the recorded path (or render it), it doesn't load some of them or make some disappear during the video. I know that it jumps back in time and therefore reloads everything, but look at this:
Please post the contents of the
fml-client-latest.log file inside the
logs folder inside your
.minecraft folder to some pastebin site and link to the post here.
Note that this log will only contain information on the last time you started Minecraft, not any previous runs.
I updated my Optifine to the latest 1.12.2 release, and I have to admit chunks loaded much much quicker and easier, but it didn't fix my issue, here is what happens:
Let's take a step back: Is this even related to Optifine, i.e. if you remove Optifine, do chunks render normally? If it is not related to Optifine, remove it during debugging.
Also remove any other unrelated mods during debugging. Same with shaders (disabling those is equivalent with removing them).
If it is indeed related to Optifine, try E1 + Forge 2768.
