v3.6.9 - Player can't see anything in the game

We're starting a game finally. I've got the initial map set up, and a player who just installed d20pro to play joins the game to test and see what it looks like.

He can't see anything on the map except his character icon. Here's what I see, RE: Fog of War. I tried showing all. Hiding all, then showing all. Revealing various zones. Nothing worked - all he ever saw was a black screen around his character.

What am I missing? I had previously tested this with my other player (albeit in a different campaign and a different map), and everything was working.

 

When I join the game as a player, plop a character model down on the map in the revealed zone, and assign ownership of that model to my dummy player, I also can't see anything.

I feel like I'm not doing something critical.

 

Alright, I loaded a second dummy map with no FoW zones and it successfully broadcast to the player when I switched maps as the GM and re-broadcast. So I'm doing something wrong with FoW but I'm doing everything the same as I did before... I thought.

I have upgraded since the last time I had it working. I was running 3.5.4 before.

 

Aaaaaand after a few more minutes of playing around, and broadcasting after every tweak to see... I figured it out. I had to disable shadowcasting for all of the zones. What I don't get about that, though, is I had put a light source in and turned it on for one of my previous tests.

Nevermind this newbie's newbidity
