scene loading problem

[sathibabu9]

I've created a 3D scene using Blender and exported it as an XML file. I want to load this scene and run a simulation or preview a Google Colab environment.

However, I encountered the following error:

---------------------------------------------------------------------------
TypeError                                 Traceback (most recent call last)

Hello @sathibabu9,

If you used the mitsuba-blender exporter to create your XML scene, in principle all meshes should be automatically triangulated. Could you please check the XML file to see if there is any shape type other than obj or ply?
For example, if your Blender scene includes special shapes like curves or spheres, these would need to be removed before loading into Sionna.
