Question Day/Night Cycle on a mobile device.

I want to research how to create a Day/Night Cycle system on a mobile device for a large map. However, I don't know how to calculate lighting or optimize shaders for mobile devices. I'm planning to use baked lighting to handle it, but I'm encountering an issue—I don't know how to smoothly transition between day and night, and I'm unsure about the performance implications of using baked lighting.

I hope to learn more about different approaches and solutions to this problem.

 

I think Unity's alpha is working on lighting transitions with AVP.
But in general for large maps, realtime lighting goes a long way. If you have 1 cascade for sharp closeup and another for further away (more cascades for higher setting) and use mobile/simple lit/custom lighting shaders you can go a long way.

 

Use Adaptive Probe value for the scene

 

Thank you for your suggestions; I have one more question. Have you tried using AVP and assessing its performance on mobile devices

 

Nope. The per vertex lighting seems to be alright for performance while still looking good
