James Webb For Kerbal is 100% dependent upon Tarsier Space Technologies by JPLRepo


Textures Unlimited by Shadowmage is an optional add-on for metallic / reflective textures and is not required.

Please download and install Tarsier Space Technologies before attempting to load James Webb.

Cacteye 2 Refocused link:



Extract the contents of the GameData folder to your GameData folder. Structure should then read GameData\JamesWebb

Optional reflective surfaces will automatically be activated with Textures Unlimited installed.
