In Unity, you can create a default lighting setup that will be applied to all new scenes that you create. To do this, go to Edit > Render Settings in the main menu and make your desired changes to the settings in the Environment tab. Then, go to Edit > Project Settings > Graphics and click the “Create” button next to the “Custom Render Settings” field. This will create a new asset that contains your default lighting settings.
From then on, whenever you create a new scene, the default lighting settings that you just created will be applied automatically. If you want to change the lighting settings for an existing scene, you can simply drag the default lighting settings asset from the project window onto the scene in the hierarchy window. This will apply the default lighting settings to the selected scene.
Note that this will only apply the lighting settings from the Environment tab. If you want to save other settings from the Render Settings window, such as the quality settings or the camera settings, you will need to create a custom graphics asset for those settings as well. You can do this by going to Edit > Project Settings > Graphics and clicking the “Create” button next to the relevant field (e.g. “Quality Settings” or “Camera”).
I hope this helps! Let me know if you have any other questions.
Hi, thanks for your answer. I looked the path Edit > Project Settings > Graphics and searched in all project settings but I couldn't found "Custom Render Settings" field.
