3 days of hard work to create this beauty, so enjoy. <3 The Anya art is original, made by me. :D And copyrighted under creative commons 3 non-commercial. So don't steal it and claim it's yours.
You can find them in game or spawn this variant of the Unity in CET with the command Game.AddToInventory("Items.Preset_Unity_Neon", 1) and the silencer with Game.AddToInventory("Items.w_silencer_04", 1)
This is just a material and texture mod, but icons are kept in bunches, not just individual images, so anything that modifies icons might not be compatible. The icons are an option included by default, you likely won't have any issues, but if it causes a conflict with another mod, you can delete Unity_Samurai_Icon.archive or Samurai Painted Base Unity Icon.archive.
Modders: The main files changed by this mod are "ml_w_handgun__constitutional_liberty__base1_01_neon1_unity.misetup", "w_handgun__constitutional_unity__base1_01.mesh", "ml_w_handgun__constitutional_liberty__base1_01_neon1_unity.mesh", "ml_w_att__power_04_01_default.mlsetup", "w_constitutional_arms_decals_n01.xbm", "item_icons10_1080p.xbm", "item_icons10_1080p.xbm", "item_icons2.xbm" and "item_icons2_1080p.xbm".
If your mod changes these icon files, and you would like this mod to be compatible, contact me (Walrus420) on the cp2077 modding discord. I'd be happy to send the source images or do the work and add the icon to your source images myself!
