Hi all,
I’d like to create a fantasy landscape in UE5. Part of that is the global illumination should not come from infinitely far away as with the sun or moon, but from a point somewhere on the terrain.
As long as the player is far from the light source I can mimic it with adjusting the angle of the sun and making the sun disc itself invisible, but it (obviously) breaks down as soon as the player comes closer.
I tried experimenting with point lights, but their max range seems to be limited and they don’t interact with the atmospheric scattering, etc.
It would be ideal if I could modify the sun light source so that it would not be directional / parallel but radiate like a local point light source would, and not attenuate too much over the distance of the terrain (currently a few square kilometers).
Does anyone know if that can be done?
If that’s not possible it could be an alternative to combine:
- a local light source (a point or a sphere) with little attenuation over the distances of the terrain (this post seems to suggest that custom attenuation is possible) - with -
- dynamically adjusting the angle of the sunlight based on the player’s position relative to the local light source
Any suggestion how to realise that would be much appreciated!
Thanks
