For example d="modular_engine_cylinder_straight" t="0"><o r="1,-1,0,1,1,0,0,0,1"

I actually meant what were the changed numbers in the xml but I actually figured that out myself. And I meant to ask what numbers were changed. Example of what I am talking about: r="1,0,0,0,1,0,0,0,1"

All Cylinders and crankshafts is modified, and some manifolds too. I've edited this in xml file.

I might've asked how you xml edited this before but which parts in the xml file was modified for the parts?

I ended up XML editing pipes, cylinders and manifolds and it all actually just works plug and play, which is insane if you ask me since instead of connecting to an adjacent part it connects at a 45 degree angle.
This build isn't only a great engine but I've managed figure out the right values to use for the angle and managed to make quite a few 45 degree parts (that aren't just engine parts) that actually work!

And it turns out I didn't have diesel in my tanks the first time :p

The translation works well.

You are an absolute god.

I hadn't thought of that. Because of XML parts, when the engine is rotated, XML parts may turn in the wrong direction. You can fix it yourself, check cylinders, crankshafts and XML manifolds/pipes, only it turns wrong. A separate copy of the parts for your own engine will work. Sorry, if it bad translated.

Well the engine I tried making runs fine with infinite fuel on so it's my own fuckup.
This is so god damned cool.

Alright, Soo, I've tried doing something similar.
How did you pull this off? I've reverse engineered the XML to try and make it a V-4, I've tried taking an entire engine and rotating it onto its side in XML, hell, I've even tried copying parts directly off of this. So how does this work? Is it just plug and play and I've actually done something wrong?

Love it.

nice
