Solar System Unreal Presentation - Release to Unreal marketplace

Quick link - Unreal marketplace

Finished work on Solar System for Unreal engine.

Features:

Distance From Target (float) is connected with Target Actor and it is used to specify the radius
where the center is target actor, in this example it is a Sun. 

Starting Angle (float) variable is used to offset planet radius.
For instance if all planets would have a starting angle set up to 0 they would all start at the same position.
So to add variety this value can be modified for each planet individually. 

Orbit speed (float) is used to set up a velocity that the planet rotates around the target(Sun),
the higher the value the faster the planet will complete a full rotation cycle.

Clockwise (boolean), if selected planet would rotate in clockwise direction around target(Sun). 

Target Actor (actor) is an actor variable that the planet will rotate around

Orbit Draw (boolean)  if selected orbit preview line will be displayed during play mode

Own Rotation Speed (float) is used to set up speed of planet rotation around it’s own axis

Advanced materials

Each advanced material relies on a source of light vector 3 values (by default 0,0,0)
so if the Sun is located in this location you do not need to change it, however if your Sun is in different
direction, change this value to your Sun location. 

Atmosphere Color (float4) - atmosphere color of a planet

Atmosphere Power (float) - related to atmosphere strength parameter, used to change the amount of atmosphere for
a planet

Atmosphere Strength (float) - related to atmosphere powerparameter, used to change the amount of atmosphere for
a planet

Base Reflect (float) - planet self reflection

BrightsideIllumination - use to change emission value for side of the planet that is facing the Sun
