Issue description
Exporting a project from headless mode prints an error when VoxelGIData is present in the project:
ERROR: Expected Image data size of 2048x64x1 (Lum8 without mipmaps) = 131072 bytes, got 0 bytes instead.

Despite this error being printed, the exported VoxelGIData is bit-for-bit identical across all export types (from headless or non-headless, towards a dedicated server build or a standard build):
