Yes it works with those two mods, since errors in mod merger are not related to texture files, so you can uncook them with W3oven without loosing textures. But it's cool actually, i never tried that. Even if you can already merge those 2 mods with mod merger, it will works without issue (there is one error about one file, but this file is merge anyway).
But in the case of COMPILATION, HDRP or UHDP, problem is still here. To get TGA files, you need to uncook the mods first with W3Oven, and by doing that you looses bunch of textures for those mods. So the best way is to do nothing, it works flawlessly if u dont merge them.
