hi when i try to copy and paste this ship in my world my graphic device crashes i tried with a different ship and didn t happen how can i solve this?

Sorry but I am using the biggest potatoe of a PC (modified IBM Thinkpad T410) for playing SE and I built this ship. Maybe your PC cant handle the game or the developers are very bad in bug fixing and optimizing. I know that this is not helpful for you but this ship has nothing performance breaking on it. In my oppinion its a stupid coincidence (bug).

idk ll try to download the ship blueprnint again and see if it works

Hi, got the ship built but i dont get the doors when i use the BP.. any idea why?

This is because the developers havent realized yet, that most survival players use builds from the steam workshop which have subgrids. The projector in survival mode only shows the largest grid on a craft. Because the doors are subgrids and they are obviously smaller than the main craft so the projector ignores them. But thanks to the glorious SE community their is a solution try the Survival Subgrid Projection mod by Gohla.

This mod doesnt change anything in your survival game except you can now print subgrids awesome isnt it? I hope it was helpful.

As of the last patch pasting in your blueprints crashes the game

Sorry, that is the bad optimization of the game. The only thing I can say is that it works on my PC, a modified IBM Thinkpad T410 from 2012 with Windows 10, a real potatoe. Please blame the developers for that!

is the only sub grid on the ship the doors or are there more that are missing

Yes, only the doors are subgrids. There are mods that allow you to build subgrids (Survival Subgrid Projection mod by Gohla: https://steamhost.cn/steamcommunity_com/workshop/filedetails/?id=2348106533) in survival but otherwise that is the fault of the game not mine.
