Select Materials without Shader from Model

[Falam]

Code: Select all

//JScript
//How do you search within the model for materials that don't have a specfic shader ?
// One thing I realize that X3DObject is strictly any [object] in the scene, similar to DOM.

oRoot =  ActiveProject.ActiveScene.Root
var sphere = Model.FindChildren("model", "#model",);
oRoot = MaterialCollection.find("Material")

I added the comments within the code snippet. The goal of the script is to search within a model, and select any materials that don't contain a specific shader node in the rendertree.

This code is completely separate, debugging test.
---------

Code: Select all

//JScript
oRoot =  ActiveProject.ActiveScene.Root
var oNull = oRoot.addNull( "thenull" );
var oCamera = oNull.AddCamera('camera','mycamera');
var link = ParentObj ("oNull","oCamera");
Root.LogMessage = ("objects parented");

Wondering why the LogMessage isn't displaying the string. I replaced the string in LogMessage with a variable, no message is logged.

I already suggested how to figure out whether a material does or does not contain a certain shader: get all shaders under the material and then search that.

Did you run that debugging snippet? Surely you must have got an error for the ParentObj call???

And since it's Friday:

Code: Select all

var LogMessage=new Object();
LogMessage.LogMessage="LogMessage"
Application.LogMessage( LogMessage.LogMessage )

Code: Select all

Root.LogMessage = ("objects parented");

what were you thinking when you wrote that?

[Falam]

Code: Select all

oRoot = Application.ActiveSceneRoot
oRoot.addNull( "thenull" );
var oCamera = oRoot.AddCamera('camera','mycamera');
ParentObj ("thenull","mycamera");
Application.LogMessage(oRoot);

Next Select Materials Script.

Code: Select all

oRoot = Application.ActiveSceneRoot
Application.LogMessage(oRoot);

Why do you want to log the Scene Root?

Just a tip, if you use a variable when you create "thenull", you'll have it as an object.
Then you can add a camera to this object and ParentObj won't be needed.

Code: Select all

var r = ActiveSceneRoot
var n = r.addNull("theNull")
n.AddCamera("camera","mycamera")

And if you are writing in Jscript and you're not planing to translate it to python, then you don't need to write "Application" all the time. Even then, you could use a variable for that.

Your making the Camera a child of the Null, correct ?

Oh, nevermind, I got it wrong.
