Scene Editor


Scene editor is designed to perform operations with the objects of the scene in 3D and 2D space.

Creating a new scene

You can create a new scene from the Start Page. Double-click on the required scene template to create.


Also, you can also create a new scene using the New button in the Ribbon and using the context menu of the Resource Window.

Learn more about creating resources.

Camera control

The camera is controlled using the Q, W, E, A, S, D or arrow keys. For raising and lowering the camera, use Q, E, Page Up, Page Down keys. You can use the mouse to move the camera by holding the mouse wheel.

To rotate the camera, hold down the right mouse button.

The most convenient way to work with the camera is holding down the right mouse button to rotate and use Q, W, E, A, S, D keys to move.

You can focus the camera on the selected object using F key or using the 'Focus Camera' button in the ribbon. By holding down F key and the right mouse button, you can rotate the camera around the selected object.

Creating scene objects

Basic way to create scene objects is through the Resources Window. Just pick a desired object and drag it to the scene.

Another way to create an object is to use context menu.

Modifying objects

Scene editor has many tools for object editing. There is the transform tool to transform position of the objects. 'Scene Editor' tab in the Ribbon, where additional tools can be found.

You can also edit objects through Objects Window and Settings Window. These windows are intended to edit any other kind of resources as well.

Transform tool

Once an object is selected, it can be modified with the transform tool. With this tool you can translate, rotate, or scale the objects.

The tool has five modes, which can be switched by clicking on the corresponding icon in the Ribbon, or by pressing R, T, Y, U, I keys. There is also a local coordinate mode.

Ribbon Move.png
Switches the control mode of the selected objects to the Move mode which allows to control the position of the objects.
Screenshot999999175 5.png
Ribbon Rotate.png
Switches the control mode of selected objects to the Rotate mode which allows to control the orientation of objects. When single object is selected then only this object can be rotated. When a group of objects is selected then the rotation occurs around a central point among all selected objects.

Ribbon Scale.png
Switches the control mode of the selected objects to the Scale mode which allows to control the scale of objects.
Screenshot999999177 2.png
Ribbon Local.png
Switches the control mode of the selected objects to the transformation mode using the local coordinate system instead of the global one. The local coordinate system is based on the space of the object.
Ribbon tab

When the scene editor is activated, 'Scene Editor' tab appears in the Ribbon. The tab has additional tools for scene editing.

Object creation modes

In addition to the Drag and Drop method of creating, there are two more: creating by clicking and creating using a brush. Modes are switched in the Scene Editor tab.

Creating by clicking is almost the same as Drag and Drop mode. For its working, you need to select the created object in the Resources Window, then click the left mouse button in the workspace.

Creating objects with a brush

Creating with a brush is the third mode of creating objects. This mode is suitable for creating many objects. Brush options are specified in the ribbon tab.

Screenshot999999999353 3.png

A brush is commonly used to create many objects of the same type. To effectively create many objects, there are special types in the editor Group Of Objects and Surface. The group of objects is a container for the effective management and display of many objects of the same type. Unlike objects created in the usual way, objects created in a group are not components. The surface is a template for creation of groups of objects, for example it is useful for nature creation.

Mesh paint

Although the brush mode is not commonly used to paint meshes, it is good for a basic example.

In order to draw something with a brush, you first need to select the desired object to create in the Resources Window, for example, 'Samples\Starter Content\Models\Fir Tree\fir_tree.fbx'. In the tab, select Brush mode, also select 'Group Of Objects' or 'Auto' in the Destination list. A brush frame will appear in the workspace, after that you can draw.

Screenshot999999999353 2.png

In order to draw into a group, it is necessary to configure its 'Base Objects', the objects on which can paint. Learn more about it.

Surface paint

The best way to use brush mode it is using so-called surfaces, which are determined by Surface type. The type of surface, or the surface, determines which set of objects will be created during the drawing process and how exactly it will be created. For example, when creating vegetation, many of similar 3D models are usually used. Placed objects can have different sizes, random rotation. All this can be configured using the surfaces applied by brush.

You can find the example of the customized surfaces in 'Content\Vegetation'. The example scene is 'Samples\Starter Content\Scenes\Surface.scene'.

Learn more about the surfaces.


Objects can be grouped using layers. To place objects in a layer, you need to select the desired layer in the Destination list. New objects will be created in the selected layer.

You can hide layers and disable the ability to select objects in the work area. A layer object with nested objects can be found in the object tree in the Objects Window.
