[1.2-1.7] Blender (2.83+) .mu import/export addon

[taniwha 2,486]

I have no idea how STL export works. However, one thing to try is exporting your imported craft as a mu, then importing that mu and exporting the result.

I cant seem to export it as an STL file. When I do it just becomes a pile of non-connected parts clipping inside of each other. Image here: My Best KSP Rocket Yet! - Imgur

I imported the craft, hit "make instances real", deleted whatever parts were too fiddly, and highlighted the entire craft and exported it as an stl.

Can you update it for 2.9 please

[taniwha 2,486]

@Grande1900You put too much stock in thread titles. It has been working on 2.9 since before 2.9 was released (deved on blender git).

Please can someone help me?

I have ksp blender and this addon and whenever I try to import a craft I get a FileNotDoundError: [WinError3] The system cannot find the path specified: ' '

I've been looking for hours on how to fix it but I can't seem to getit to work

@UltraGeekIt's mentioned several times throughout this thread but your problem is most likely that you have not set your KSP GameData path in blender via the options panel where you enabled the addon (you'll have to open the panel as it is collapsed by default).

@UltraGeek Unfortunately, there aren't any clues in there to help find the problem part (not your fault, python's),

After looking at the code in the area suggested by the exception and doing a quick test on my system, I suspect that either the model referenced by the MODEL node is missing, or it has the wrong case: while windows is case-insensitive, linux (what I use all the time) is not, and nor is the database.

I ran into an other issue(the last one was caused by me not following the install guide and setting the game's folder not the gamedata folder)

I've seen that someone has had this issue and they've posted what they did to fix it but it's not too clear what they did to fix it.
