Custom Engine Issues- 0 Acceleration.

[Jack3663]

Hi everyone, my group is attempting to make some custom parts for KSP but we having a few problems. We have managed to import a model into KSP no problem but, the part is an engine btw, when we attempt to fire the engine it will not produce any acceleration even though it says its giving out the correct amount of thrust I set in the CFG. file.

Our file structure is GameData\Strato-Labs\Parts\Engine\SLE109MarkI and in side there is the model11.mu and the mbm. file for the place holder texture. If it helps the original output file from 3DSMax was an obj.

This is my first time at creating a part.cfg and although im sure everything is correct I can't be 100% sure, so can anyone offer any explination as to why this might happen?

This is the part.cfg file (it is still a working progress and most of the values are based on stock engines for the moment):

Thanks guys!

thrustVectorTransformName = thrustTransform

This is the usual cause of the problem. This line tells the game which object to apply the thrust to, so if you're not getting any thrust applied it's likely that this object is misnamed (it's case sensitive, so ThrustTransform wouldn't work) or missing entirely (outside the exported hierarchy, forgotten etc.).
