For the IUS parts, they have to be in different configurations, three total in fact (each representing the two stages and the final one is the TDRS itself). Transitions would be made by using the EVENTS parameters
Since sc3 and VB isn't working for what I want. I may just built a simple dll with the IUS first stage. Make it so if fuel is out detach 2nd stage. or press a key it detaches. Might need to do it for the 2nd stage also.
SC3/4 worked except for the pivot point of the ASE.
VB might work but I could get the animation to work like the DLL
MS2015 might work but it is made to launch from a pad and not in space and attached to the ASE.
I am going thru the many meshes. Is there a fix to this. I may need to go back to the drawing board. The shades of grey are what I am talking about. Like the one Payload door,..... I need to fix the textures also
