Monochrome Mode Warning in HDR Film Output

[madhumitha-murthy]

Hi,

I’m seeing the following warning when loading a scene in Sionna:

2025-04-10 19:55:36 WARN wrk0 [HDRFilm] Monochrome mode enabled, setting film output pixel format to 'luminance' (was rgb).

This occurs after I load my scene using load_scene("scene/sample_scene.xml", merge_shapes=False).
Could you assist me in resolving this issue?

Thank you in advance for your help!

Hello @madhumitha-murthy,

It is safe to ignore this warning.
If you would like to avoid it, I believe you can comment out the <sensor> or <film> block in sample_scene.xml.
