Been a long time since I did this without my script but...

Open your Command Prompt (found in Start Menu\Accessories or type cmd [Enter] in the Start Search or Run box). Now lets use the   change directory "CD" command to navigate to the converting folder. This is not   case sensitive. Note that you can also use paste [Ctrl + V] at the command   prompt.

CD C:\Developer\ConvertXSI [Enter]

 navigate to the folder your files are in. Or is the .xsi file and convertxsi.exe in your C: dir?

C:\WIndows\System32>c:\convertxsi tradeship_PSI.xsi tradeship_PSI.mesh

you can use without CD but need addresses on command

C:\WIndows\System32>C:\WherIsConvertXSI\convertxsi c:\MyModels\tradeship_PSI.xsi c:\MyModels\tradeship_PSI.mesh

or move done mesh to diff folder

C:\WIndows\System32>C:\WherIsConvertXSI\convertxsi c:\MyModels\tradeship_PSI.xsi c:\MyGames\SoaSeMods\NEWtradeship_PSI.mesh

Any addresses wit spaces need quotes around "c:\progam files\my model.xsi"

also, how do we move the point or 'hardpoint' where a ship spawns the 'warpfield' to jump to phasespace etc? for certain models I'm working on in my mod the warpfield generator is in the middle of the ship instead of in front of it? I feel like this is a very basic issue but I can't seem to find any info on moving the point? is it tied to P001-Ability-0? or something else entirely?

hmm, no I meant the phase field that is generated in front of every ship before it jumps to phase space....unless that 'point' is located at ability-0 by default?

Hmm k thanks for the info so far though, if anyone else has any information I'd really appreciate it. and yep it's for rebellion...I've been working on a ton of models and imported them successfully but it just seems the warp point is all over the place
