thank you so much!
it's the SEUS v10.2 Ultra shaders, a very old shaders pack, but decided to use them as i'm a huge SEUS fan and i generally like these shaders.
however there's some issues that i must warn you about, first, this shaders pack is almost completely bugged in the nether, end dimensions and also underwater, so i suggest turn these shaders OFF when you're in these areas
*i've used bsl shaders for the nether, and complementary reimagined for the end & ocean pics.
also it has a shading issue that happens in a certain time of day and angle (it doesn't happen all the times though) so i had to take these screenshots in a specific time of day/ angle in order to make it less noticeable

you can try other seus versions too if you still want the look of the SEUS v10.2 Ultra, maybe the newer ones doesn't have such issues, but i couldn't use them as my laptop can't handle them

hope i've helped! please have a great time!

thank you so much! glad that you like it
please have a great time!

hii
i’ve used seus v10.2 ultra for the overworld screenshots, it’s outdated though, with some shadowing issues (in the above screenshots i had to take them in a specific time of day & angle to get the best results)
it’s completely bugged in other dimensions (the nether & the end) and underwater too so in the nether screenshot i’ve used bsl and for the ocean and the end i’ve used complementary reimagined.

you could try seus v11 or seus renewed or seus ptgi, i think they will give you kinda the same look and feeling of the v10.2 ultra, however i didn’t try them so i can’t tell if some of them is bugged as well or not

or you can try v10.2 when playing in the overworld (yeah there’s some shadowing issue as i said but it’s in a specific time/ angel, it doesn’t happen all the time/ in all angles) but consider turn the shaders off or switching to other shaders when playing in the nether or the end

please have a great time

this is exactly what im preparing for v4!
also i want to expand Nature X too, currently it focuses mainly on the nature elements of the game, and i want to expand to include other unrelated elements too! such as mobs, items, and adding many variations of textures too.

so that’s what i’m currently working on, besides preparing Nature V which is a vanilla version of Nature X that doesn’t require Optifine but with less features.

thank you so much for the comment!
