By using "Edit packing method " in flow item bin you can create new packing method or change exsidted packing method by writing the code on " custom code".

Then you also have to change the packing method at palleta in flow item bin.

Great! Thank you so much, I change some locations for myself and how to flip the space? Because for me the space is between rows (and now is between columns), and z dimension. Next Layers go 0.1 to much "up". where to change those things?

Object item = i;
Object current = c;
Object lastitem = item.prev;
/**Default Packing Method*/

// Check to see if the flowitem is the first one in
if (current.subnodes.length == 1) {
item.setLocation(0.05, -0.1, current.size.z);
item.setRotation(0,0,180);
return 0;
}

//First row
double xlength = 0;
double ynumer = 0;
double xnumer = 0;
double znumer = 1;
int space =0;
for (int i = 1; i <= current.subnodes.length; i++) {
xlength = xlength+item.size.x;
if(xlength<=current.size.x){
space = ynumer/2;
if(ynumer==0&&xnumer==0&& znumer==1){
xnumer++;
}
xnumer++;
item.setLocation(xlength-item.size.x+0.1, -ynumer*item.size.y-space*0.2-0.1, current.size.z*znumer);
item.setRotation(0,0,180-180*Math.fmod(xnumer,2));
} else {
ynumer =ynumer+1;
if(ynumer<4){
xlength =item.size.x;
xnumer= 0+ Math.fmod(ynumer,2);
space = ynumer/2;
item.setLocation(xlength-item.size.x+0.05, -ynumer*item.size.y-space*0.2-0.1, current.size.z*znumer);
item.setRotation(0,0,180-180*Math.fmod(xnumer,2));
}else {
ynumer = 0;
znumer ++;
xlength =item.size.x;
xnumer= 0+ Math.fmod(ynumer,2);
space = ynumer/2;
double xnumer = 0;//pierwszy na górnej warstwie
item.setLocation(xlength-item.size.x+0.05, -ynumer*item.size.y-space*0.2-0.1, current.size.z*znumer-0.1);
item.setRotation(0,0,180);
}
}
}

You need to change the formula the"Space" and the place where it is included in the pattern.

In attached I also send you the secound version of the mode.

Thank you very much! great code.

One more question - how to change the Z.

Because first layer goes perfectly on a pallet (pallet is 0.13 on Z) and item is 0.03. but the second Layer goes on 0.26 on Z, but it should 0.16. and the third goes on 0.39, so it also adds 0.13 but it shuld be 0.19

You can try a change in every "item.setLocation"

"current.size.z*znumer" to "current.size.z+item.size.z*(znumer-1)"

In this way, you set "z" location of the first layer as pallet hight and the next layers as pallet hight plus items hight.
