That’s my guess, anyway, I could easily be wrong. The fix is to link to a texture with a new, custom TGI. Default replacements that link to the EA texture TGIs are overridden by the 0x2BC04EDF resource with the same instance. CASPs that link to textures seem to be looking for the new resource type first and using an RLE2 only if it doesn’t find one. With the new patch the EA eye and makeup RLE2 textures are now empty and there’s another resource (type 0x2BC04EDF) with the same instance number that afaik is a new type. Not yet tested on alien or animal eyes. Eye colors - Default Replacement + Non-default and Glowing Eyes for Vampires (Default Replacement + Non-default) To use these Vampires’ glowing eyes,you need The Sims 4 Vampires Game Pack. Please save as a new package and keep the original just in case. This is very quick and dirty, so please consider it to be beta-ish and report problems. Replace the original package with the new one in your Mods folder.

When the tool is finished save as a new package. Select your default replacement eyes package. To use, extract TS4DefaultEyesFixer_1_0_0_0.exe from the zip and run it. Some more of mouseyblues leftover eyes converted to ts3 brntwaffles. This is a very simple tool to fix default replacement eyes that were broken by the June 3 patch.
