You have to set the toolbox set to IMS in StackEditor/StackEditor.cfg
Also, a suggestion for an improvement... perhaps add a UI to help you make sure you have enough heating/cooling/power generation/life support, and to calculate your stack dV?
I can't access the inline J-2X
or the boosters.
Huh... I can't access some parts from the IMS pack, even after setting the toolbox properly. I can't access the inline J-2X or the boosters.
You can download J-2X and some other stuff not included in IMS distributive by using the link at the bottom of my post.
Is the mesh in there too? because then it should technically work. That pack has been the default distribution of IMS for quite a while noe...
