Texture animation

I have multiple images that I’d like to texture map to a sphere and change with time. What I get from this post Draping a sequence of textures on an evolving surface in an animation is that simply loading the images as a group in the (pickable) texture dialog won’t work.

Is there a simple way to do this or should I try to hack a solution via the python interface?

Okay, so I managed to get a work around by calculating the values of the texture on a sphere and exporting the results as vtkPolyData, but loading one .vtp file per step in the animation is rather slow due to the high resolution…

I figure updating a texture would be much faster, so any direction to look into is highly appreciated…
