"When custom Door Mods are not maintained anymore you must create Piston based as game has no native rails.

Using 1x Large advanced Stator with attached Small head as base.
6 pistons 2 from rotor head and 2 additional to make desired wide opening.
2 pistons as locks that goes to hole made from large half block.

Doors look nice but are based on subgrids and game do not like this.
Will be nice if there posibility do design airtight doors from small blocks and then place them as normal large 3x2 blok doors.

Toolkit for game to make custom 3D model with static animation is for building game like this is old technology."
