Here is the object I created for our game, it may not look like much, but it will be the main collectible in the game. It is a pile of gold that will glow and make a sound when collected.
Here they are in Unreal, where a gold texture has been applied, and they have a light added above them to make them "glow." I have also made them blueprints, and added code to make them collectible.
(A picture will be added here when all group members have created their assets and uploaded them to git)
