As a 3D artist at Intercept Games, I had the chance of creating models, textures and implementing a wide array of space-related assets, that can be used to add unique utility functionality to the players' spacecraft. Here are some them.
An extendable ladder used to climb to or descend from a command pod that is not accessible at ground level in Kerbal Space Program 2.
An external command seat that can be externally attached to a spacecraft or rover, allowing to control a vehicle.
An external battery pack used to provide a larger electricity charge capacity to a spacecraft or rover.
