Create A Floating Material in Unreal Engine 5
I wanted to highlight something I thought was super cool inside Epic's Action RPG example of how they created a bobbing potion inside the material.
Software Version: Unreal Engine 5.4.4 | 4.27
Looking at Epic's Action RPG I thought it was super interesting how they tackled the floating potions in the game. Instead of using a tick function or timeline, they did it all inside the material. Doing everything inside the material, I believe, puts all the computation onto the GPU.
To accomplish this feat the material uses the Time node along with Sine and Vector3 parameter. All three nodes used together along with some calculations can produce a result that can be plugged into the material's World Offset Position.
Changing values in the Velocity param can lead to the mesh moving at different rates and/or different directions.
Overall, I just thought this was an awesome method that I wanted to highlight and isolate. Using this technique can lead other unique material changes.
