3D models of SpaceX Starships and boosterThere are 3 Starship variants available.

• The crewed version
• The cargo version
• The tanker version

The crewed version has a simplistic interior with sleeping arrangement and common areas. The cargo version has a cargo bay and the cargo bay door can open as seen in one of the renders

With all the variants there are exhaust effects for the raptor engines and also for the vacuum engines. There is also exhausts effects for the super heavy booster as well as reentry effects for the Starships. Remember these effects work in Blender cycles. But it renders fast so not much of a rendering panelty there.The exhaust effects are also already animated.

There are also rcs thruster exhaust effects available which you can find in the deactivated collection in the outliner.

The clouds in the preview renders are not available since those are just free stock image. However the space scene with earth is included as a 360 invironment, change 3d viewport to perspective view to see it.
