Welcome!

I usually use a `Node` to update the scene. This example works for me:

```julia
using GLMakie

n=100;

function meshgrid(vx::AbstractVector{T}, vy::AbstractVector{T},
                  vz::AbstractVector{T}) where T
    m, n, o = length(vy), length(vx), length(vz)
    vx = reshape(vx, 1, n, 1)
    vy = reshape(vy, m, 1, 1)
    vz = reshape(vz, 1, 1, o)
    om = fill(1, m)
    on = fill(1, n)
    oo = fill(1, o)
    (vx[om, :, oo], vy[:, on, oo], vz[om, on, :])
end

x = range(0,1,length=n);

X,Y,Z = meshgrid(x,x,x);

vrt = sin.(2pi*X) .+ Y .- Z.^2*(rand()+im*rand());

vrtx = zeros(n,n,n,n)
for i=1:n
	vrtx[i,:,:,:] = real.(vrt.*exp(im*2pi*i/n))
end

dat = Node{Array{Float64,3}}(vrtx[1,:,:,:])

scene=contour(dat,alpha=0.2,colorrange=[-1,1],colormap=:balance,levels=[-0.5,0.5])

record(scene, "/tmp/kir.mp4") do io
	for i=1:n
		dat[]=vrtx[i,:,:,:]
		recordframe!(io)
	end
end

```

By the way: There are some tips and tricks how to [make it easier for others to help you](https://discourse.julialang.org/t/please-read-make-it-easier-to-help-you/14757). For example you can format your code and it would be easier if you give an example that works (we don’t have your `sample_vrtx_1.mat`, needed to run your code).
