Files needed to be edited for increasing size of the map in CK3?

[RedWalrus]

I was able to change the map size in Imperator by almost 4 times the size, but following the same techniques, I am not able to. Has anyone been able to do this? What files are needed to be edited?

I am currently getting these errors in my error.log.

Further testing seems to show that for some reason the memory in ck3 is more limited than imperator? I'm trying a smaller map to see what happens... My original map was BIG. 16000x9856 lol I'm trying 9600x5888

Sorry for the late unearthing of the post.

I am having the same issues right now, I have searched many places on the forum but can not find a definitive answer as to what is the max map size (length x height) or if there is a max « buffer » size as you mention (maybe 250Mb file, 500 Mb… I don’t know).

I’m currently trying a 16384 x 8192px. No success. Not either with 12288 x 6144 (50% bigger than vanilla). Although some mods managed to load 16384 x 6144, I was not, some file (don’t know which one) keep failing over and over. I strongly suspect the .dds water, foam etc, which would be 2.2x or 4x vanilla size respectively, but even downscaling these did not help

Have you been able to figure out a solution to your issue and
