Problem with render illumination. Illumination changes in the render.

Hi everyone,

I’m very new to Unreal Engine, and this is my first time posting here. I recently made some models in Maya and wanted to render them in Unreal Engine using the Movie Render Queue. However, when I did the render, I noticed that the illumination keeps changing.

I’m using Ultra Dynamic Sky. For the foliage I am using free assets from Fab. I already set the camera exposure to manual, but the issue persists. I also tried adjusting various settings and looking online for solutions, but I haven’t been able to fix it. I can send the settings that I have set right now on the Ultra dynamic sky, but almost all the settings are set to default.

Does anyone know what might be causing this? Also, I’m not sure if this is the right place to ask, so please let me know if I should post elsewhere.
Thank you very much.
