Documentation does not match my installation for "Material" customization

[italosand]

Hello,

I've installed the open3d library throug pip (version 0.17.0) and I'm struggling with the documentation. I'm using the python version in windows, and I can't find out how to change the lighting/meterial properties. I'm following the tutorials in the documentation wich in some version refers to a class in open3d.visualization.rendering.Material and other times refers to a class in open3d.geometries.TriangleMesh.Material (I'm using triangular meshes). But the only one I found in my installation was
open3d.visualization.Material and open3d.visualization.rendering.MaterialRecord. Also I couldn't find out how to use those in something like open3d.visualization.draw([{"name":"heart", "geometry":mesh, "material":material}]), as it awais returns, when adding the "material" property:

RuntimeError: Unable to cast Python instance to C++ type (compile in debug mode for details)

I don't know what to do, I just want to change the lighting to a less "reflective" one...
