Need explanation of model scaling

[linuxgurugamer]

This has been bugging me for a long time, but today I got asked this question and was unable to properly answer:

 

Seems like there are 3 places where one can alter scale:

• Within the Model {}
• using scale
• using rescalefactor

I've been able to make changes using trial and error, but different solutions appear to work for different parts and I haven't found a repeatable pattern.

Can someone explain each, where each should be used, and the advantages/disadvantages of each?

Thanks in advance

Hello dear sir,i'm not a modder but i made some custom rescales to parts to fit my needs.
From my experience:

scale = // usually 1(1=m,0.1dm,0.01cm),it defines a parts original size and its not used to alter the parts size
rescaleFactor = //is used to rescale a part,final scale of model will be orig_size * rescaleFactor

this is mainly used if the model (model.mu) is located in the same directory as *.cfg.

So the better way is to alter the parts size trough MODEL{}

MODEL
{
model =  //the path to the model
scale = x,y,z //scale of the model in 3 dimensions(height,length ,width)with this you can resize each axis individually
}

final scale of model will be orig_size * scale_in_MODEL_node(default: 1.0,1.0,1.0) * rescaleFactor

I usually use only rescaleFactor for rescaling.

I hope this will help you.
