Brutal Replace
"Use this simple tool to make 'brute force' replace in similar objects. This will copy the master object to the target objects positions - making exact copies of the master in the same position of the targets. Only work with mesh.
Ex: You may have 30 twigs in a low poly tree. You did one twig and copy the others - moving - rotating - scaling - bending each one to build the tree. Then you need to change a little the UVW for the twigs - or change any setting that not alterate topology. So you change one twig - select it as the master object in this tool - select all the others and run. Done! Now you have all the twigs in the same position - with the same name each one had before - but everyone a exact copy of the master."
