@Frazart The way I play with these shaders is like changing them for every map. Like for Tranzit/Die Rise/Buried I use the basic BO2 shaders (but with better quality), for Nuketown I used the old gen shaders for testing and I thought like it would be cool if the perks were the yellow ones from SoE at the beggining and when you reach round 25 the perks would turn blue to match the zombies eye color changing. For Mob I also use SoE shaders since the BO3 remake used them and it matches perfectly with the map. For Origins, at first I thought the old gen would fit better, but the default ones also works well, it looks like I'm playing the BO3 version.
But for all of them to work properly, I'm still searching for the SoE Tombstone shader to add to this pack, but I think I'll have to make a custom version of it because I can't find it anywhere.
