So i have use a standard transformation matrix in openscad, which uses a
matrix processed by multimatrix.

the standard trs matrix can be rotated and placed with this:

i have to write a quaternion lookrotation function for openscad, unless
there is another option. i can export the positions and rotations to any
format from Unity3d so perhaps will use the fct's from it.

ok so here is a complete parser for position of unity transforms, it writes
up to 2000 or something objects to text in assets folder that can be copied
into a scad array and csg'd there. for the moment just tested the cube
centered and it works ok.

//clear matrix text prior to every rewrite, see end fct:

for (var i =0; i < depth; i++){

//obj2 = the object to get the transformation matrix from
	
	
// takes the matrix coordinates and formats them into .scad matrix array

string
var mtrs : String = "[";
var loopcount = 0;
var number : Matrix4x4 = obj2.transform.localToWorldMatrix;
mtrs = mtrs + "[" ;
for (var l =0; l < 4; l++)
{
mtrs = mtrs + "[" ;
for (var m =0; m < 4; m++)
{
loopcount += 1;
var numbertext = number[l,m];
numbertext.ToString();
mtrs = mtrs + "" + numbertext + "," ;
if (m==3){mtrs = mtrs.Substring(0, mtrs.Length - 1);};
}
if (loopcount == 16)    { mtrs = mtrs + "]],\n\n";}    else    {mtrs =
mtrs + "],\n";} ;
}
writeMatrixTxt(mtrs);

}
mtrs = mtrs.Substring(0, mtrs.Length - 3); mtrs = mtrs + "];";//delete one
char, the comma and close array

writeMatrixTxt(mtrs);

//squareoff ();
//offset();
}

function writeMatrixTxt(wrstring : String){

File.AppendAllText(Application.dataPath +"/MATRICES.txt",wrstring);

}

function clearMatrixTxt(){

File.WriteAllText(Application.dataPath +"/MATRICES.txt","");

}
