I have a 3D scene in JavaFX and need to overlay GUI over the 3D scene. I have tried adding buttons and text to the scene but they always appear in the 3d view as 3D objects. I have looked around and haven't found how to do it. The only workaround would be creating a whole new window and putting the settings there but that isn't an option in this case. Thanks for the help!!
Something like this
Or this
The best solution for what you are looking for is the SubScene, a built-in JavaFX container:
The SubScene class is the container for content in a scene graph. SubScene provides separation of different parts of a scene, each of which can be rendered with a different camera, depth buffer, or scene anti-aliasing. A SubScene is embedded into the main scene or another sub-scene.
If you have a look at the 3DViewer project, you'll find it is like the pictures you have posted:
You can find a small sample of how to add a subScene to a regular scene in this question.

I'm trying to make a centered grid pane in the JavaFX scene builder which stays a fixed size. I'm having a hard time doing this myself. Anything I can do?
I'm trying to accomplish something like this:
You can use stackpane as parent of your gridpane
I have a 2D GUI declared in an FXML file. The GUI contains a pane, I want to make a 3D scene within the pane. How would I go about doing this?
Use a SubScene, which, like a Scene has a camera, depth buffering, etc.
I'm trying to make an window, where I have StackPane as root and I want to add MenuBar to this window. However MenuBar is in the center of the screen and I want to keep it in the top part of the window as in normal Windows applications.
root = new StackPane();
root.getChildren().add(new MenuBar());
this will show window like this

Thanks you for your advice!
I would say StackPane is not suitable for making a GUI including a menubar.
StackPane will just put the controls you add to it one on top of the other.
In java docs you can find:
"StackPane
The StackPane layout pane places all of the nodes within a single stack with each new node added on top of the previous node. This layout model provides an easy way to overlay text on a shape or image or to overlap common shapes to create a complex shape. Figure 1-6 shows a help icon that is created by stacking a question mark on top of a rectangle with a gradient background.

I have an application that uses a javafx Scene to render something, and I want to put that rendering into some GUI that I made, also in javafx. How would I do that?
Basically is there some container I can put a scene into and then put that container into the GUI.
Sorry if it's a newbie question, I am new to JavaFX
Java 8 has a SubScene, for which some possible uses (from the javadoc) are:
The SubScene class is the container for content in a scene graph.
SubScene provides separation of different parts of a scene, each of
which can be rendered with a different camera, depth buffer, or scene
anti-aliasing. A SubScene is embedded into the main scene or another
sub-scene. Possible use cases are:
Mixing 2D and 3D content
Overlay for UI controls
Underlay for background
Heads-up display
A SubScene is just a Node, so you can place it in the scene graph of an existing scene wherever you want. An example of SubScene usage is in the answer to: How to create custom 3d model in JavaFX 8?
Generally SubScenes are for mixing 2D and 3D content. If you are not doing that, then SubScenes probably don't apply to your situation and Uluk's answer will better serve your needs.
The scene has only a top parent node as a root. You can get it and to put into another scene.
((Pane) scene2.getRoot()).getChildren().add(scene1.getRoot());
I am trying to create a splash screen like the example I've provded.
It seems that AnchorPane does not allow transparent background, I've tried setting the css of the AnchorPane to -fx-background-color: rgba(255,0,255,0.1) ; but the white background still shows up.
All I have in my fxml file is a AnchorPane with ImageView with contain the png image
I've looked everywhere but can't find any solution, any help would be appreciated. Thanks
Try this JavaFX splash sample created for the Stackoverflow question: Designing a splash screen (java). And a follow up sample which also provides application initialization progress feedback.
JavaFX does offer the Preloader interface for smooth transfer from splash to application, but the above samples don't make use of it.
The splash samples above also don't do the transparent effect, but this dialog sample shows you how to do that and you can combine it with the previous splash samples to get the effect you want.
The transparent effect is created by:
stage.initStyle(StageStyle.TRANSPARENT).
scene.setFill(Color.TRANSPARENT).
Ensuring your root node is not an opaque square rectangle.
Which is all demonstrated in Sergey's sample.

How to use javaFX Preloader with stand-alone application in Eclipse?
Update Apr 2016 based on additional questions
the preloader image isnt in the foreground. I have tried stage.toFront(), but doesnt help.
A new API was created in Java 8u20 stage.setAlwaysOnTop(true). I updated the linked sample to use this on the initial splash screen, which helps aid in a smoother transition to the main screen.
For Java8+
For modena.css (the default JavaFX look and feel definition in Java 8), a slight shaded background was introduced for all controls (and also to panes if a control is loaded).
You can remove this by specifying that the default background is transparent. This can be done by adding the following line to your application's CSS file:
.root { -fx-background-color: transparent; }
If you wish, you can use CSS style classes and rules or a setStyle call (as demonstrated in Sergey's answer) to ensure that the setting only applies to the root of your splash screen rather than all of your app screens.

how to make transparent scene and stage in javafx?
You need to have transparent Stage and Scene for that. Pane itself doesn't have a color.
public void start(Stage primaryStage) {
Button btn = new Button("Say 'Hello World'");
AnchorPane root = new AnchorPane();
root.getChildren().add(btn);
// Java 8: requires setting the layout pane background style to transparent
// https://bugs.openjdk.java.net/browse/JDK-8092764
// "Modena uses a non-transparent background by default"
root.setStyle("-fx-background-color: transparent;");
Scene scene = new Scene(root, 300, 250, Color.TRANSPARENT);
primaryStage.initStyle(StageStyle.TRANSPARENT);
primaryStage.setScene(scene);
primaryStage.show();
}
