Within UE4 I have created some visual effects to help give the level a bit more animated movement. The first effect I created was the flame and ember effect for my Torch Asset. Most of the effect was created using panning textures and blending masks within UE4's material editor as well as embellishing the effect with the particle cascade editor. The embers were created with a simple set up using a radial exponential node in the material editor and setting it to orbit within the cascade editor both with a particle colour input. To give the light flicker effect from the point light as seen below on the tent, I used a simple light function set up with a time input that effectively fades the light on and off dependant on the input you multiply it with. The final effect I created was to add simple wind to the trees and foliage. This effect was quite subtle but overall really helped the dynamic aspect of the level as well as emphasising the tranquillity of an autumn sunset setting which complimented the original aesthetic of the level. To create this effect, I added a 'simple grass wind' node with number parameter inputs that let me control the wind weight, intensity and the world offset position allowing me to get a wind that matched the water effect and still looked visually appealing.
