custom engine producing no thrust

[tychodin]

so this is my first custom part. i'm creating a radially attached engine, and i just used the Rockomax Mark 55 cfg file as a template. and while the tooltip in game says the part is producing 80kN of thrust, the craft doesn't go anywhere, and it's acting like there's no actual thrust. here's a link to the cfg file:

what am i missing here?

Is the thrust transform on your model named thrustTransform?

[mouzfun]

You can change it in the cfg file itself here, right?

thrustVectorTransformName = thrustTransform

Anyways, you should add empty gameobject in unity, position it so the Z axis (i think) would be a direction of the exhaust, name it as specified in the .cfg file, and you are done!

ok so i made the model in blender. what exactly is a thrust transform?

[tychodin]

do i just need to make an empty in blender with the name node_thrustTransform or just "thrustTransform"?

[blackheart612]

Thrust transform is where the exhaust FX come out and the directions the Engine pushes. I make thrustTransform empty (pointing in the right direction) in unity to be free of blender-unity import problems. I think the blue one is the correct direction (was it z?). Anything under the thrustTransform node in the hierarchy will be moved when the engine is gimballed. Gimbal angle is set on config.

"thrustTransform" can be of any name BUT it should be set on the config with the name you used as stated above a couple posts back.

ok so i tried making an empty single arrow pointing in the correct direction, but it's still not picking it up. the .dae file has the transform node

<node id="thrustTransform" name="thrustTransform" type="NODE">

<matrix sid="transform">1 4.15965e-16 0 0 0 0.4871138 -0.8733385 0 -4.15965e-16 0.8733385 0.4871138 0 0 0 0 1</matrix>

</node>

so i'm not sure what the issue is. i don't have unity installed, so i'll keep looking for a blender solution for now.

[tychodin]

i wonder, does the transform need to be a child of the mesh?

[NoMrBond]

I'm not sure if .dae files work with the necessary transforms anymore?

[tychodin]

is that because of the tensor form of the transform? because i think it can be expressed as a vector instead.

You need unity to use PartTools. This way you can simply use the mu-format. It's much more simple than fighting with DAEs.

[tychodin]

bah, if the transforms don't even work, i guess i'll have to bite the bullet and learn how to use unity.

[NoMrBond]

Using empties within Blender does work if you're using Unity to export your .blend files to .mu files

Just use this tutorial:

(unity stuff is closer to the end)

Unity import is quite simple, actually. The final result should look like this http://i.imgur.com/Ju93pbl.png
