I tried using the old power render software from TC2M but it doesn't want to export the .lsl files completely as it should, probably because the files are slightly different/updated?
I believe it was posted by norb at some point that this engine just uses the slightly updated power-render version 6
Anyway, I think I found that map modding is not yet allowed maybe?
I tried putting in a map I created on my own w/ power render 6 and using the old packer utility...although it works I can't access my map in-game.
