Simple Batch Render
When you need to render out pictures from one or many blenderfiles this addon on makes it very easy to make a .bat file that can be executed from inside Blender or as it separate .bat file started with a click from your desktop without having to open up Blender first.
Simple Material Replacement* Addon stores and reuse material names on obejcts. Once set it is simple to write back materials to objects that already are in the material data base.
Using “Rigged Systems Addon”, it is easy to create movements on, among other things, cylinders. You can easily import respective pre-defined systems for cylinders, turnbuckles and universal joints. Even simple features are included like, " Cursor to objects mesh ", " Empty to object ", " Selection to selected ", “Selection to selected - And copy rotation”. Also there is a feature that “Add Rotating axis” amongs selected directions. Also the features “Empty to object” and “Add roating axis” works in edit mode.
