Just updated to the latest ioquake3 (I was using a build from 2015) and all my specular maps are broken. See images:

Anyone know whats causing this? It looks as if specular maps are simply being overlayed on top of the map textures, rather than being applied properly...

This is Spearmint v0.2:

This is Spearmint v0.3:

Try reinstalling IOQ3 to see if there is something wrong with your game files.

Otherwise if you’re sure it’s a bug, here is their issue tracker:
