Function: These days, many online game or pack game include weather change, day time change effect on it.
For example, sandbox(cryengine) have this funtion in the engine, so people can change easyly the option.
-Amount of light
-Sun azimuth
-Clouds "interpolated" sky tecture
So, I try in the UDK using material and kismet, mantinee. Using VectorParameter in material box have the limitation which texture only change A to B, A to Z. Switch VectorParameter to ScalaParameter. It is little bit better than using VectorParameter but, still have to figure out how to make it smooth day/night change in UDK
Material Nod
primaryPanorama which I give the sunrise->sunset texture(8 textures, using Lerp, scalarParameter)
Kismet& Matinee
But most frustration problem is the material is not showing up, separated cloud,sky material, it wasn't still working on it.So I have to change my plan to making cloud movement nice and clean.
[Cloud movement node]
[Cloud movement speed->param'Cloudpan_x': ScalarParameter]
[Cloud moving]
[Conclusion about this project]
Need more experence about UDK and kismet information. Have to figure out what is the problem which sky is not moving and changing.
