For the life of me I could not enter the passcode to get into the train. I may be missing an item or something. Otherwise the other dimension effect was neat. Did you use a shader, or is that done with a script?
Hi, you can see the code when you are in the other dimension, in the wall (it is 1542), and yes it is a shader made it with shader graph, it is a normal dissolve shader with a movement with time.
