I am putting together a ‘Solar System’ project, and am using a blueprint that creates a realistic star/sun that burns at 3000K, and is complete with solar radiation/flares.
The sun takes centre stage (0,0,0) in the scene and at the same co-ordinates is the sky sphere, that has a ‘purple nebula effect’. The sphere itself is scaled up to around 100K. I have made four other space materials for the sky sphere, of which are interchangeable via the ‘C’ key, and controlled via the player controller blueprint.
When the level is played the sun, shows it’s full detail (solar radiation/flares), however, when I change the space material, the suns effects are almost lost, e.g. becomes dim, and radiation subsides, though flares are faintly seen.
I have noticed also, that as you look away from the sun, the sky sphere material, goes from dark to light, this exposure happens over a few seconds.
Another observance was that if I change the inital sky material and then hit play, the sun’s effects are fine. Problems only seem to occur when the material is changed.
I’d like to know how to retain the sun’s effects, no matter whet sky sphere is selected, and also like to keep the sky sphere at a set exposure.
Please could any of you out there help provide a solution for this? Thank you in advance.
