As suggested by Amerk, here are two tutorials you'll definitely find interesting if you want to draw the best out of RMVX.
If you are a beginner, the official guides
will cover the basics. It is strongly suggested to read it before asking any question on the forums.
For more advanced users, a thorough guid
e made by Kelsper and Benko is available on our tutorials forum
. It's very large (over one hundred pages) but you don't have to read it in one run. Again, it is more directed to intermediate users who want to learn how to use the full potential of the engine.
