Hi everyone!
I’m working on a scene in Unreal Engine 5 where the camera moves forward through a landscape, and the environment dynamically changes with the seasons. I’d like to understand how to properly set up and animate all these transitions using Sequencer (or possibly Blueprint + Sequencer) to achieve smooth and natural changes.
Scene overview:
- The camera moves forward smoothly.
- Trees change by season: Spring → Summer → Autumn → Winter → Winter Night.
- In Autumn, rain and falling leaves begin.
- In Winter, snowfall starts.
- Lighting changes over time:
- Spring – soft morning sun.
- Summer – bright daylight.
- Autumn – sunset.
- Winter – evening light.
- Winter Night – moonlight and visible stars.
- The background skyline (Dubai) needs to transition into a night version by Winter Night.
- Background sky (HDRI or skybox) should also update as the seasons change.
- Foreground trees also change:
- Spring – pink blossoms
- Summer – green foliage
- Autumn – yellow leaves
- Winter – bare branches
What I need help with:
- How to properly manage mass switching of assets, materials, lighting, and weather using Sequencer?
- How to animate weather effects (rain, snow) – should I trigger Niagara systems via Sequencer?
- How can I swap sky images (HDRI/skybox) using keyframes?
- Any advice on performance/optimization when setting this all up?
Extra:
If anyone with experience doing something like this is available, I’d love to chat directly (Telegram, Discord, etc.) — I’m trying to set this up correctly and efficiently.
Thanks in advance for any help!
