Changing Vector Fields according time

Hello,

Here’s the situation: I have wind vector data that I want to view in Unreal 4.19. I can easily convert this data into direction vectors in each time step, and then into a format Unreal can read (apparently it’s .fga - Fluid Grid ASCII). However, this data is fairly large (there are 721 time steps, and each is split into 94 x 192 for latitude x longitude, and this on the small side). Is there a way to have Unreal load all of this data and display each step, or must it need each time step as a separate file? The ultimate goal is to have the user cycle through each the time steps and see each vector field at that time step. One more question: Must the fga files have a cubic resolution or is a non-cubic resolution allowed?
