Unwrapping modular pieces for tiling textures

C86G · Jun 2019

Hello guys.

I got a problem and need your help. I want to unwrap a piece of geometry that is a part of a modular building (at this stage its only a grayboxed model).
I want to use tiling textures and so I need to make the tiling wall piece to fill exactly the horizontal space uv the UVs. How do I do that in Max?
I know there are some snapping options. But I dont want to moce vertices, I want to scale the whole uv chunk.

What am I missing here?
Thank you : )

Hi, Try this:

(
	if(selection.count != 0) then
	(		
		/*max modify mode;*/

		modsCount = $.modifiers.count;
		print modsCount;
		unwrapsCount = 0;
		if(modsCount == 0) then
		(
			addmodifier $ (Unwrap_UVW());
		)
		else
		(
			for i = 1 to modsCount do if(ClassOf $.modifiers[i] == Unwrap_UVW) do unwrapsCount += 1;
			print unwrapsCount;
			if(unwrapsCount == 0) then 
				addmodifier $ (Unwrap_UVW());
		)

		$.Unwrap_UVW.unwrap2.setTVSubObjectMode 3;

		selectedPolys = $.Unwrap_UVW.unwrap2.getSelectedFaces();
		if(selectedPolys.isEmpty) then
		(
			$.Unwrap_UVW.unwrap.selectPolygons #{1..polyop.getNumFaces $};
		)

		selectedPolys = $.Unwrap_UVW.unwrap2.getSelectedFaces();

		x = 0.0; 
		y = 0.0;  
		w = 0.0; 
		h = 0.0; 
		aUVW = 0.0; 
		aG = 0.0; 
		$.Unwrap_UVW.unwrap4.getArea selectedPolys &x &y &w &h &aUVW &aG;
		/*format "X: % Y: % W: % H: % aUVW: % aG: %" x y w h aUVW aG;*/

		S =  (1.0 / w);
		$.Unwrap_UVW.unwrap2.scaleSelectedCenter S 0;

		$.Unwrap_UVW.unwrap4.getArea selectedPolys &x &y &w &h &aUVW &aG;
		/*format "X: % Y: % W: % H: % aUVW: % aG: %" x y w h aUVW aG;*/
		$.Unwrap_UVW.unwrap2.moveSelected [-x, -y, 0];
	)
	else ( print "Selection is empty!"; )
)

object should be edit poly / editable poly
select uv-shell inside UV editor and run the code.

Will try tomorrow when I am back at work.
Thank you!
