So I'm currently implementing a full daytime change in my scene and I'm now wondering how to approach this problem.

Before what I had was my static scene with a skybox where I could use this skybox (or better use an env probe) to create prefiltered environment maps and irradiance maps for diffuse ambient and ambient specular lighting respectively. But now as the scene and the environment becomes dynamic I stand before the problem of not being able to use the old static approach to this. My current idea is to make 3 environment maps for 3 "special" daytimes like night, sunrise/sundown and daytime and interpolate between those. Is this a viable idea, or do I have to do it differently ?

 

My second question would be if there is a better way to render the environment from the probe itself then to rotate the camera and render 6 times the scene for each face ? As I understand I have to do this without any post-processing enabled ? What about tonemapping ?
