Simplify Complex Scene Creation with Custom Material Support (based on #821 and #850)

[steffenitely]

Hi everyone,

Apologies for chiming in a bit late, but thank you for the fantastic work on Sionna 1.0!

I’d like to bring up a small quality-of-life request based on issues #821 and #850 . In versions prior to 1.0, adding custom materials was relatively straightforward. It was easy to build complex scenes in Blender with multiple objects, each using various custom materials not included in the predefined ITU materials. Since the objects in the XML file referenced these custom materials directly, it was simple to assign them just by scanning the file.

However, with Sionna 1.0, only scenes using ITU materials can be loaded. This means users now need to either manually list all objects that are supposed to use custom materials or modify the list of supported materials before the Sionna import—both of which make the process of updating scenes or adding new materials more cumbersome.

To make creating complex scenes easier in the future, it would be incredibly helpful if Sionna could still load scenes that reference non-ITU material names.

Maybe this issue has already been solved by an easy fix and if so I'd be grateful for some help

Best regards!

Hi @steffenitely,

Thank you for reporting the issue.
This is a bug, as it should be possible to load scenes using custom radio materials. It will be fixed in the next release.
