RawRzly

So, this might sound stupid but bare with me. So, most of the time I don't ever really feel like modeling unless its for RL stuff . So I thought "Hey join SL again!" to try and force me to make more models.( Get better with modeling and learn a few things.) The problem I'm having is I don't know how to go about it. And every video I come across is pretty outdated or uses a different software. So I guess what im asking is what's the process? Do I have to install additional plugins? Can I just import/export from my software to SL? And will all my maps work? I know it seems dumb. But to tell you the truth I tried learning this the first time I was on SL but with no luck, lack of information, and almost no skill. Any tips or suggestions would be really appreciated.
