Realistic Sub-UV's. How did Epic make theirs?

This has been an ongoing question I’ve had for months - How do Epic make their Sub UV’s such as explosions, smoke, etc.? I’m interested to know what program they are using. Did they make it from scratch? If not, How can I make ones similar to theirs? I tried using Photoshop, After Effects and just plain Cascade in UE4 to reproduce a similar effect but to no avail. Anyone know about this? Thanks :slight_smile:

Most are made in after effects, what you’re doing is creating a simulation and then rendering that simulation frame by frame and then arranging each of those frames into a grid creating your sprite sheet(or flip book texture or as unreal calls it a sub uv texture) and then using a dynamic node in cascade. make sure you set your dynamic node to however many frames your sprite sheet is (6X6,4X4X, etc…)
https://youtube.com/watch?v=xmjntIQkfcsthis is a link to a nice video on how to make a smoke sprite sheet, I know it says for unity but don’t worry about that because the sprite sheets are universal. Hope this helps you if you have any more questions regarding particle effects feel free to pm me
