Our Internet service was down for six or so days. That was the only time this year I’ve been productive.

I started playing around with Blender’s Python scripting and wanted to do something really basic just to see if I could do it. With help, I did. I present to you: Select objects by type.

It just pops up a menu and selects all the objects in the active scene that are of the type you select in the menu. I was working on multiple selection but Blender’s built-in toggle buttons — “Draw.Create(True/False)”  — hate me.

It doesn’t work with 2.5. I (kind of) tried to get it working, but I have to say I feel bad for the people porting stuff over.

It’s noobish. It’s ugly. It’s useless. It’s buggy. It…works at least. 😀
