Blue tint of vanilla suit has been removed. Two 8k resolution cape options. Different cowl textures can be mixed with different cape textures to find your optimal look.

Texture requires 'Texmod' to work. Download Texmod, run the application and select package mode. Select BatmanAC.exe as target application. Go to the small folder icon and search for the extracted files. Choose your preferred suit and cape options. Run the game through texmod.
Two cape options currently available. The studded version is similar to what's found in the Remaster, though there are smaller gaps between the grains. Threaded version gives the cape a threaded look. Might add more cape options in the future.
I've tested around 80 different cape textures, trying to chase the remastered cape look. The normal map bump height just can't be increased to suit the remaster, and the texture gets distorted in action.
