I searched the PyVista documentation, with the integrated search.
I already searched in Google "How to X in PyVista" and didn't find any information.
I already read and followed all the tutorial in the docs and didn't find an answer.

Write a short description telling me what you are doing, what you expect to happen, and what is currently happening.

print("Create pyvista volume")

vol_rgba = np.vstack([img.reshape((-1, 4)) for img in img_list])
vol = pv.ImageData(dimensions=[w, h, depth], spacing=spacing_array_xyz)
vol['colors_rgba'] = vol_rgba

p = pv.Plotter(off_screen=True)
p.add_volume(vol)

p.show()

p.export_html(str(visualization_path/'volume.html'))

Description

I'm trying to export an image stack volume to interactive html file using the export_html function in a workstation without screen. However, the exported html file show nothing when I open it in Chrome or Edge browser.
