Hi,
I have this issue. When applying 'paint' to a window frame or an other object I have soms strange shading that doesn't belong there.
I cannot figure out how to fix this.
Changing material to plastic keeps the shading, other materials do not have these shadings (glass, diffuse, etc...).
Is there something I'm missing?
