[BUG] Issue with the generation of the "Color Attribute" node as Blender 3.4 in Cycles

[LengaJenga]

• I am using the latest version of the exporter

Bug description

As of Blender 3.4 the Cycles render engine requires the "Color Attribute" node to have a value selected to properly display the vertex colours in rendered view and will no longer work by default with an empty value. This can be fixed by selecting the value Col in the "Color Attribute" node.

If someone is not new to Blender they may not realize the issue as it still displays properly in the material preview mode.

Steps to reproduce

1. Import any environment into Blender 3.4
2. Set render engine to Cycles
3. Set viewport mode to rendered
4. Notice the lack of colour/shading

The current behavior

Currently, there is no value assigned by default when importing an environment.

The expected behavior

The expected behavior is that the value Col is selected in the "Color Attribute" node by default when imported. That will fix the issues.
