Thank you @lanlyn.
The special effects worked better than I'd hoped. I was going to have fires all over town too but worried about lag with so many fog emitters.
I've left the town just as you last saw it in the video so if the future story requires me to go back for his family I should be able to do it. If they are still there.
I had a few problems with Anna Mation. Firstly, I gave her a makeover and put her into the Big Game. Then I played with other games for a few weeks. Then I went back and got her from the Base Camp where I thought I'd left her. But she wasn't the made over version.
Then I found the made over version living at the boarding school. That confused me and I was thinking of how I was going to deal with the situation. I sent the unmadeover version back to Moonfall Island but somehow the game decided it didn't like her being there while I was recording Dan's efforts to meet his parents. When I got Dan back to Moonfall Island Anna Mation wasn't at the Base Camp and I haven't seen her since. She just vanished. I have no idea what happened to her. But I needed one of them to vanish so I decided to not worry too much about it. Now I'm wondering what'll happen to other sims. Probably nothing as I've never noticed a problem before and she was a doppelganger who shouldn't have been in the game.
Now I'm working on a chapter to give some of Eric's back story since he's about to become a main character in Oscar's story. I've wasted most of today in my effort to record some video of his early life. I found an old save with his parents in it and it was from before I broke the game up into several worlds. There are so many sims in a huge world my computer can't run it with my mods in - even with all graphics down to minimums. So, in desperation I used MC to do Total Annihilation of most of the town's inhabitants then bulldozed their houses so the game can't put new sims into those empty houses. I'll be able to delete this save when I'm finished recording as I won't need it again and I still have a few copies of the original save untouched.
Happy Simming
