Inner parts of polygons appearing black when importing Shape file

[AtelierCartographique]

Hello,

I'm having an issue when importing Shape files in Blender through BlenderGIS.

Here's the shape file in QGIS:

And here's how it renders in Blender:

The inner parts are all rendered in black. Is it a known issue with BlenderGIS, and is there a way to fix this in Blender?

Thanks a lot!

I know I'm a bit late, but are you able to share the example shape file? I'm curious if I can replicate the issue on my machine.

This is a know issue, the script can handle multipart geometry but if the part defines a polygon hole then a new face will be created. This case is difficult to handle when building the mesh. Also, according to the shapefile spec, the points of a polygon are ordered clockwise and the points of a polygon hole are ordered counterclockwise, that's why this "hole face" has a negative normal and appears black.
