Hello everyone. I have a customly rendered table, and I am trying to figure out how to connect two tables if they are placed next to each other, similar to a fence or iron bar. I haven't seen much on how to do this, but I think I have it half done. The table that I place down next to it will update it's model accordingly, but the other one that is already there won't. Here are some screenshots of the situation: Tables when not connected: Tables when connected: As you can see, the other two adjacent tables are not updating their model, even though they should be. So I guess I have two questions: 1. How can I change a currently existing block's model? 2. If I'm doing this the complete wrong way, what is the best way of doing it? Here is some of the code that I currently have: BlockTable: ModelTable: TileEntityTable: TileEntityTableRenderer: Thanks in advance for any help.
