How to scale part models in CFG? [1.3]

[UbuntuLinuxKing]

Hi,

So, I'm trying to scale the model for one engine to fit the 3.75M form factor. The original model is 2.5M, and I would like to resize it in the CFG so that both the attachment nodes and the model scale to match. Anyone know how to do this?

Thanks!

You can use rescaleFactor = xxx

where x is for the correct scale between 3.75/2.5m. The nodes stay the same so you don’t have to tinker around with those

What do you mean by this?

He means that you have to use the right scale factor to scale it from 2.5m to 3.75m.

In this case it would be (3.75/2.5), ergo:

rescaleFactor = 1.5

As far as i know, you also have to scale the position values for the nodes (the first three values), therefore you have to multiply them also by 1.5. e.g.

from:

node_stack_top = 0.1, 0.32, 0.2, 0.0, 1.0, 0.0, 2

to:

node_stack_top = 0.15, 0.48, 0.3, 0.0, 1.0, 0.0, 2

You can also set the seventh parameter to 3 to have the node in the size as the other nodes in the 3.75m scale

When using rescaleFactor, the nodes should stay in their correct positions relative to the part.

this was not the case with changing the scale values of the model itself.

@Nightside Oh, that is something i did not know yet. Thanks for the clarification.

Using just rescaleFactor worked when sizing UP a 2.5m to 3.75m, but sizing them DOWN didn't work, even after I multiplied the node_stack definitions like @Nils227 said.

How would I use that math to scale down a part? I have a 3.75m part, and I want it to be 2.5m. So I run it through a calculator (2.5/3.75) and I get 0.66 repeating. Would just 0.66 in the CFG do, or am I doing my math wrong? EDIT: 0.66 didn't work AT ALL. It did absolutely nothing.

Yes .66 should work. Check to make sure u didn't change scale instead of re-scale. Also, u don't need to change anything in the attachment nodes.

No, I definitely changed rescaleFactor. Maybe it's just the model - I'll try a different one.

The ideal RescaleFactor for 3.75 to 2.5 is actually .65

Never mind! Again,my own stupidity - the part model was broken.

There is another method if you're feeling creative.

MODEL
	{
		model = Squad/Parts/Resources/ISRU/ISRU
		scale = 0.25,1,0.25
		
	}

 

Standard values are 1.0. In this example the following shape is the result:

And in case you're wondering why I did that:

I turned the ISRU into a cyclotron and the ion engine into a nozzle. It's a proton cannon.

And one day you must share with us the how to for those amazing compound (assembled from many parts) assemblies you create,  the pipework on your engines for example.
