I used RMXP pretty extensively; I just got MV today. I know the mapping system hasn't had the layer system since RMXP. However, can someone please explain the letters on these tiles?? Does this majorly affect importing tiles? When there was a red background in the RMXP tilesets, I could just put it on second and third layer. In MV, I am on the A level but some of these cliff tiles have a red background I can't get rid of. Why would they be in there if I can't get rid of them? If someone could answer these questions and maybe point me to a solid tutorial on all the basics of mapping in MV specifically that'd be great. Thanks!
