I have a desk lamp that’s giving me issues. I wanted to check here before I updated the source and filed a bug report. I’m currently using a self-compiled 64 bit version on Debian - 2.67.1 r57442.
This lamp has two materials - one for the lamp, the other for the flat section inside the lamp that has an emit material. There’s a subsurf modifier set to ‘2’, but no other modifiers. The light from the emit material shows through the back of the lamp at the edges.
Here’s a picture showing the underside of the lamp in solid mode so you can get an idea of how the mesh is put together.
Is this expected behavior, or should I update my svn and file a bug report if it’s still happening?
