Not sure why but I cant get it to do a day to night transition. Its as if the lighting is not being calculated correctly. The clip length is 10 sec. maybe I need to have it way longer then speed it up in post?
If I select the initial frame of the clip it looks like this.
Hi, I noticed that the HDRI background is static, it DOES NOT ROTATE according to the rotation of the sun, so check the option if the lighting is in HDRI, I have in the solar one. Maybe there’s something that bothers him when you move from frame to frame.
I would use the solar system without HDRI, with clouds set to move in a certain way.
Good work
It seems strange to me that the clouds remain the same point. But do you take two frames, where one has the sun at 8:00 and the second at 20:00?
In this way you have a daytime scene and another night scene with 10 seconds of video, check if it works this way, but you definitely have to adjust the scenes with the final light that comes on at the end, just save the second one with the lights on in the evening.
Actually, it’s a currently known issue that there may be unsmooth transitions between shots when keyframing the environment (Geo and Sky/HDRI) to create the effect of time changes.
This is because it is relatively difficult to downsample in this case (when the scene environment changes), thus white spots/scene flickering may occur during preview or output.
Suggestion: When keyframing the environment in animations, if white spots/flickering occurs, it is recommended to output separate video clips and combine them using the post-production software.
