About this Mod

This mod adds a new block to the game, which is kinda interesting: the RGB Block. For now you can only get it in creative mode, but that will change very soon. You might think: why do we need this block when we can do the same but with maps? Well, it makes the process way more simpler, faster and better and it works more effectively since you just place a couple of blocks, but to get the illusion, make a wall out of these blocks and step away, you will see the illusion form right on your eyes!

Server lagging with RGB Block – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if RGB Block consumes the most tick time.
