To start seeing a model you can drop any file from Game/Assets/Models into the screen. Alternatively you can load a scene going to File -> Load -> Scene and choosing the .scene file you want to use.
Scene navigation controls resemble the ones from unity:
- Move the camera as fps game using right click + W, A, S, D
- Orbit the model using Alt + mouse motion
- Pres F to focus on model
The engine is based arround hierarchies of game objects that have a set of components asociated to them. All game objects will have at least a transform.
You can edit the game objects distribution via the scene hierarchy by dragging them or using the contextual menu that pops up with right click. You can also select objects by clicking them on the scene (As long as they have a mesh).
To tweak components or create them you can select the desired game object and go to the inspector, Each compoentn has its own set of options.
Alternatively you can modify the transform using the guizmo, to change its current mode use the buttons at top left of the scene or the W, E, R keys.
