Hi, I have some results from a simulation that represent a 3d surface object moving in time. When I try to record the mesh much like the example in the documentation I don’t seem to get the plot actually updating. It displays one single frame. I am pretty new here so there is probably something I am missing.  
Thanks in advance.

using Makie, GLMakie  
f, ax, pl = mesh(verticies\_i’,faces)  
record(f, “uv\_mesh2.mp4”, 1:100:length(bd1)) do i  
verticies\_i=(bd1[i].Tib_verticies\_b’+bd1[i].sbr\_i_ones(1,n))’  
# mesh!(ax,verticies\_i’,faces)  
end

You’re overwriting the vertices variable, you need to turn it into an Observable and update it not overwrite it.
