I'm a beginner in Blender and seeking advice how to properly make certain areas of a mesh transparent.
I have a house, which is built out of a cube. In Edit mode I've added planes to represent windows. These planes have material glass.
I would like to put a light source inside the house, however, as the material of the house is not transparent, the light does not come through the windows.
I tried to cut areas of the house where the windows are through loop cut and subdivide, but as the windows have irregular shapes, it requires ages to cut and introduces too many polygons.
Thank you for any ideas!
