How to grab the texture map of a surface

V3Digitimes

I'm sorry I cannot help here. Maybe try to save your material as a depreciated material preset to see what is written in the dsa, it may give you an idea how it is set up.

WTH does this tell me? And can I use it somehow to find out more information?

TypeError: Result of expression 'myShineStrMap.setTopCoatBumpStrength' [undefined] is not a function

It means you tried to use a function "setTopCoatStrength" on myShineStrMap - something like

myShineStrMap.setTopCoatBumpStrength( .1 );

but there's no such function. If myShineStrMap is a material, use

// get the propertyvar oSetTCStr = myShineStrMap.findPropertyByLabel( "Set Top Coat Strength" );// Assuming we go the propertyif ( oSetTCStr  ) {// Check that it's the right type to have a numeric valueif ( oSetTCStr.inherits( "DzNumericProperty" ) {// set the valueoSetTCStr .setValue( 0.1 );}}

where Set Top Coat Strength is the label on the lsider you want.

I saw there was an example script to get all the available properties, etc of a given node. http://docs.daz3d.com/doku.php/public/software/dazstudio/4/referenceguide/scripting/api_reference/samples/properties/node_properties/start

I assume one can do the same thing for a material.

I've just posted a Material Properties sample. Notice that both it and Node Properties have/use the same getElementProperties function (which in turn calls getGroupProperties).  This function can be used on any DzElement derived object; what changes is getting to the element to get the properties from.

Thanks, Richard and Rob!

 

I'll check out that new example.

I had found most of what I needed by altering the script Rob gave elsewhere, but it wasn't quite what I was looking for.

Feeling so noobish... but then my primary scripting language has always been vbScript and mostly web programming (its been years since I did any of that, though).

Richard,

 

can I include your load preset script as part of my script/product? With proper accreditation of course.

Richard Haseltine

Yes, that's fine.

evilded777

Thanks, Richard!

On to the next question.

If I want to REMOVE an image map from a channel.... what would that expression be? I tired setMap(null), but struck out.

V3Digitimes

oProperty.setMap( "" );

:)

Thanks, V3Digitimes.  Very helpful.

So... shouldn't this work:

 

if iSpecMap != (""){

blah blah

}

Because I have no clue what isMappable() is actually supposed to do...

evilded777

And one would think

if isMapped()

run against a variable of which you can .getMapValue(), ought to work also.

WTH am I missing?

 

Richard Haseltine

Are you sure iSpecMap is a property and not just a string with a name? The inequality in the first post suggests the latter, in which case the isMapped, getMapValue etc. won't work on it. It is very important to do error checking - not just that you have something but, using .inherits( object name ), that it is the right kind of something (use inherits rather than isA as that is more fault-tolerant - for example, using isA( "DzSkeleton" ) would initally reliably find all figures, as distinct from a bone or other object type, but OptiTex dynamic clothing introduced a new figure type and now, in DS4, there are no more dzSkeleton objects as everything is a derivative so any script that uses isA( "DzSkeleton" ) will now fail to find any figures, while those that use inherits( "DzSkeleton" ) will continue to work).

Richard,

 

yes, that is really where I am falling down... this whole inheritance thing, and how to properly determine what I am looking at.

 

I need to examine that carefully.

From what I experimented - and rememeber- when I can ".getmap" of something, I have no error message when using "ismapped".

What is the exact error message you have?

 

Richard : incredible piece of information! So inherit is in general safer, and now I see why. I did not know and I don't used it a lot. I hope I won't get in trouble.

evilded777

Obviously I don't understand the usage of isMapped().

if ( oProperty.inherits( "DzNumericProperty" ) {	bMapped = oProperty.isMapped();	// Do stuff}

In the above, the if statement checks to see if what I have is of the type DzNumericProperty; got that.

What is bmapped = oProperty.isMapped() doing? I'm guessing we are setting bMapped to a boolean value depending on wether or not oProperty has an image map value. Is that correct? Because that does not seem to work for me.

And just using the if part gets me a Parse Error.

I mean... what I am doing works, but to be efficient, I really need to test is there is an image map in certain places and if not, look somewhere else for the image.

Below if what I have so far. Its much improved thanks to Rob and Richard.  But... I really need that part about checking to see if a certain property of the material contains an image map, and I just can not figure that out.

function setMaps(){	// get the number of selected Nodes	var iNode = Scene.getNumSelectedNodes();	for( i = 0; i < iNode; i++) {	var oNode = Scene.getSelectedNode( i );	if( ! oNode){		return;	}	if( oNode.inherits("DzBone") ){		oNode = oNode.getSkeleton();	}	var oObject = oNode.getObject();	// If we don't have an object	if( !oObject ){		// We're done... exit early		return;	}// Get the current shape for the object	var oShape = oObject.getCurrentShape();	// If we don't have a shape	if( !oShape ){		// We're done... exit early		return;	}	var iMat = oShape.getNumMaterials();		for( j = 0; j < iMat; j++){			mMaterial = oShape.getMaterial ( j);			oProperty = mMaterial.findProperty( "Bump Strength" );			iBMap = oProperty.getMapValue();			oProperty = mMaterial.findProperty( "Top Coat Bump");			oProperty.setMap( iBMap );			oProperty.setValue( 1.21 );							oProperty = mMaterial.findProperty( "Glossy Color" );			iSpecMap = oProperty.getMapValue();			oProperty = mMaterial.findProperty( "Glossiness" );			oProperty.setMap( iSpecMap );		}}	};setMaps();

 

Richard Haseltine

Yes, bMapped will be true if there's a map and false if not. So you'd want something like

if ( oProperty.isMapped() ) {     iBMap = oProperty.getMapValue();     oProperty = mMaterial.findProperty( "Top Coat Bump" );     if ( oProperty.inherits( "DzNumericProperty" ) ) {          if ( oProperty.isMappable() ) {                oProperty.setMap( iBMap );           }     } }

evilded777

Awesome. Thanks, Richard.

 

Got pretty much exactly what I wanted.

If only there was a way to tell if an artist has put in a "place holder" image.
