Hello,

I'm trying to code a crawl. I've created a project with a scenegroup (just the group, no extra scenes in it) and a second scene that has the text object on it like you would normaly add to the scenegroup.

Now i am trying to load the scenegroup, and load the scene, and try to add the scene to the scenegroup, and I get the message Unable to attach scene to non template SceneGroup "SceneGroup1".

This is the code:

[CODE]

// Get the SceneGroup as a scene (is there an other way?)

engine.GetSceneByID(1, out scene);

// Turn the scene in a group

scenegroup = (xpSceneGroup)scene;

// Get another scene with textline, twice

engine.GetSceneByID(2, out scene1, true);

engine.GetSceneByID(2, out scene2, true);

// Fill the scenes with text

scene1.GetObjectByName("Text1", out obj1);

tekst1 = (xpTextObject)obj1;

tekst1.Text = "This is the first line of this crawl.";

// Insert scene in the SceneGroup

scenegroup.AddScene(scene1); //

That error msg indicates that the scenegroup was not a "copy" of a scene group. You can only use addscene on a "copy" of a scene group. However, your code looks correct since you call GetSceneByID which by default makes a copy of the scenegroup unless you add the option third parameter and set it to false.

I actually added your code as is to a c# project and it works fine for me. I checked scenegroup.SceneCount and it was correctly set to 1 after you call AddScene.

Try checking scenegroup.IsCopy after the GetSceneByID call to ensure IsCopy is actually set to True.

You can also try changing `engine.GetSceneByID(1, out scene)` to `engine.GetSceneByID(1, out scene,true)` to explicitly set the scene to be a copy..

Thank you Brian. However the default of AsCopy in GetSceneByID is 'false', not 'true'.

So changing the code to

engine.GetSceneByID(1, out scene, true);

solved my problem.
