Ghost Triangles in 3D view
Hello,

I am using SH3D v4.2a (from getdeb.net) on Ubuntu 12.04 64-bit, Oracle Java 7.
When looking at the 3D view of a house I'm modeling, there sometimes appear strange floating triangles connected to corners of rooms. Those triangles are visible only from specific angles.

I attached a house design and a photo (aerial view) showing such a "ghost" triangle, which seems to be connected to a room corner under a black railing end. The issue is consistent - if you load the attached model and put the 1st floor at aerial view from the point shown in the photo, you should be able to see the triangle.

Those triangles also seem to be consistent - they appear also in the virtual visit and are a real problem when taking photos.

Can anyone please explain why those triangles appear and how to make them go away? Last time I had one, it seems to be because of tiny partial overlap between two rooms. However, this time it does not seem to be the case.

Regards,
Erez Hadad
