Simple Script Example - Add LIE Layer to Existing Texture

bohemian3

Hi all - thanks for all the posts here, learning so much.

I found the document for LIE DzLayeredTexture - but there's not an example there, unfortunately of how to implement.  I can probably work from this documentation to create what I need, but I thought I'd ask if someone already has a simple script to do the following.  I know you can save a LIE preset but unless I'm doing it wrong, it seems bound to the current object and surface - you can't seem to save a 'generic' overlay.  I want to add a grunge layer on top of whatever surface I have selected through script.

1) Add an Image layer - Source Over
2) Add an Image Mask - Source Over
3) And Save

That's all.  Also, I can't use my iRay diffuse overlay because I'm already using that for something else.

If you by chance have that, I appreciate it.

@Richard Haseltine - Thank you so much - Here's the final script - It adds an additional grunge LIE layer on top of the current texture to any surfaces that are selected.  Still to do: More robust error checking and cleaning up orphans if another layer is added.  Again, thanks

oNode = Scene.getPrimarySelection(); 
var oObject = oNode.getObject();
print (oObject.name);

var oShape = oObject.getCurrentShape();	
nMaterials = oShape.getNumSelectedMaterials();

for (var i = 0;  i < nMaterials; i++)
{
	var oMaterial = oShape.getSelectedMaterial (i);
	
			var aProperty = oMaterial.findProperty("Diffuse Color");				

              if (aProperty.name == 'Diffuse Color') {
					oTexture = oMaterial.getColorMap();				
					addOverlay(aProperty,oTexture.getFilename(), "Grunge.jpg", "GrungeMask.png");
					print ("----------");
					print (oMaterial.name, oTexture.getFilename(), aProperty, oTexture.name)						
              }							
}

function addOverlay(diffuseProp, currentTexturePath, imageGrunge, imageMask ) {

	print (currentTexturePath, diffuseProp, imageGrunge, imageMask);
	var oImageMgr = App.getImageMgr();
 
	var sBasePath = "C:/Users/YourHomeBase/OneDrive/Pictures/";
	var sBaseLayerPath = String("%1/%2").arg( sBasePath ).arg( imageGrunge );
	var sMaskLayerPath = String("%1/%2").arg( sBasePath ).arg( imageMask );
 
	var oBaseLayerFile = new DzFileInfo( sBaseLayerPath );
	var oMaskLayerFile = new DzFileInfo( sMaskLayerPath );
 
	var sBaseLayerName = oBaseLayerFile.baseName();
	var sMaskLayerName = String("%1 Mask").arg( oMaskLayerFile.baseName() );
 
	var sTextureName = oImageMgr.getUniqueImageName( "Grunge" );
	var oLayeredTexture = oImageMgr.createLayeredTexture( sTextureName );

    diffuseProp.setMap( oLayeredTexture  );					
 
	oLayeredTexture.size = new Size( 4096, 4096);
 
	if( App.version64 >= 0x0004000600020017 ){
		 if( !oBaseLayerFile.exists() ){
			// We are done..
			return;
		} 

		var oOriginalImage = oLayeredTexture.createLayer( "Original Image" );
		oOriginalImage.imageFile = currentTexturePath; 
 
		var oLayer = oLayeredTexture.createLayer( sBaseLayerName );
		oLayer.imageFile = sBaseLayerPath; 
 
		if( !oMaskLayerFile.exists() ){
			return;
		}
 
		var oMask = oLayer.createMask( sMaskLayerName );
		oMask.imageFile = sMaskLayerPath;

	} else {
		var oLayeredImage = new DzLayeredImage();
 
		if( oBaseLayerFile.exists() ){
			var oImageLayer = new DzImageFileLayer();
			oImageLayer.filename = sBaseLayerPath;
			oImageLayer.label = sBaseLayerName;
			oLayeredImage.addLayer( oImageLayer );
 
			if( oMaskLayerFile.exists() ){
				var oImageMask = new DzImageMask();
				oImageMask.filename = sMaskLayerPath;
				oImageMask.label = sMaskLayerName;
				oImageLayer.setMask( oImageMask );
			}
		}

		oLayeredImage.toLayeredTexture( oLayeredTexture );
	}
}

@Richard Haseltine Okay - I just read the license -  If I were to distribute my version with a freebie I'm working, the way I read this is as long as I include a link to the original script and license with a note of changes made, I can do that?  Am I reading that correctly?

If you download the script, rather than copying and pasting, the header already has most of the required information - obviously not your changes.
