This Wintersun patch for Requiem 4 is based on Seg's original patch as found here:

Original Requiem Patch (Skyrim LE): https://www.nexusmods.com/skyrim/mods/95859?tab=files

This mod resolves the conflicts between Wintersun - Faiths of Skyrim and Requiem.

You will need the original Wintersun mod (installed above Requiem.esp): https://www.nexusmods.com/skyrimspecialedition/mods/22506

Then this patch installed below Requiem.esp.

What has been done:

Converted the original mod to SSE format.
Reassigned missing master files.
Fixed and cleaned missing references.
Harmonized with SSE converted version of Requiem 4.0.2.

Please let me know if you find any bugs.

Thank you to EnaiSiason for Wintersun.

Have fun.
