Hi,
I was in doubt of opening a new discussion or add to this one. Well …
This is not black geometry but related to display issues.
I’m checking a zone geometry types with the HB_decomposeByType component.
Next image shows that the Preview is OFF for the component. Only the Windows are shown with the PreviewGeometry. The color of the window was set with the ColorSwatch as blue. The image shows that for Wireframe and Shade display some windows are rendering as expected and some are not (white or magenta colors).
Next image, following above description, shows Rendering display. For this case ALL geometry shows, even though only windows are supposed to be.
-A.
Credits for the geometry to @bussey.philip. I was checking his discussion here, so decided to continue with this thread.
