So I’m relatively new to Unreal 5 (and Unreal in general), but have made a lot of headway so far, but I’m playing with creating a virtual set and thought it would be cool if the walls in one of the hallways like began to drip black fluid/blood at a certain point, and haven’t been able to find a good tutorial to follow to make something like that happen. Any information or starting directions to follow would be much appreciated! I’m assuming it’d require something involving decals or Niagara? My fallback is since the final output is a video to just do it in post-production via AE, but having it in engine I think would be a lot less time-consuming.
I wanted to chime in on this in case others came here looking for this too.
I couldn’t find any tutorials on this exact function (maybe I’ll revive my old tutorial channel and make one soon), but after some research and logical reasoning, I think I have a solution.
You can utilise Gif animations into a spritesheet, ie. a gif of blood bleeding, then separate the frames into individual pngs, import to UE and turn them into a flipbook.
From there you can use that flipbook in a material decal and just simply slap in onto a wall, you can have full control in BPs over the speed of the drip or even when it begins to play from an event trigger.
If I end up making an actual tutorial I’ll be sure to return and post it here.
