ViktorVovk	5c71a4da56	Allow to unload scene resources when a scene is exited (#7381 ) * This adds two new settings, available in the Project Properties and in the Scene Properties dialog, to allow to specify the strategy for preloading resources of the scenes and unloading them. By default, a game will preload in background the resources of all scenes. It will never unload these resources (so scene switching is fast). * You can now choose to unload the resources of a scene when the scene is left using the "Resources unloading" field. If the scene is launched again later, it will load its resources again. * You can also choose to change the preloading to disable it for all scenes (by modifying the setting in the project properties) or enable it/disable it on a scene by scene basis. This can be useful for large or modular games where you anticipate the player to only play some scenes, or if you want to reduce the resources that needs to be loaded on a web game.	2025-07-02 16:09:52 +02:00
Neyl	dff99b79cb	Add basic support for shadows (#7592 ) * Shadows are rendered for 3D objects when a Directional Light is set up on your scene layer - which is now the case by default for new games and new layers: they will have both a Directional Light and an Ambient Light. This renders shadows like it could be done by the sun. * 3D models and 3D cubes are now casting shadows. To see them, you must ensure you the "Standard" material type in their configuration (and not the "Basic", which means they don't react to light) and be sure to enable "Shadow casting" and "Shadow receiving". This is done by default for new objects you create or import from the Asset Store. * Shadows are rendered around the camera on an area that is large enough for most games while giving still good quality results. This means they should work out of the box and be adapted to most games, including large maps. You can adapt the quality of shadows, intensity of the light (and so shadows), the size of the rendered area by editing the Effects of the layer in the scene (as for other effects).	2025-07-02 15:49:26 +02:00
