As the title says, everything from here (retaining walls and the riverview/Twinbrook items) ain't showing up, when I did everything I had to (and yes Riverview is installed).

However I downloaded some WAriverside walls by Gelina on a blogspot and they ARE showing up without a problem...

I'd appreciate it if somebody could help me out :/

I'm trying to figure out caw basics as well, there is some time since I worked on this last. There is a difference between caw objects and game objects. CAW has it's own framework. I just installed it and is now trying to figure out if it's working. What kind of objects did you download, and is the caw framework set up in your game?

You can find lots of tutorials here: http://modthesims.info/showthread.php?t=463191
and on the wiki: http://simswiki.info/wiki.php?title...3_CAW_Tutorials

Remember caw is an old program and things might have been changed as time went by, the trick I think is to find out what's "old, but still work" and what is "old and outdated".

It's also quite easy to set up regular CC to show up in CAW I think. As I say I it's a long time since I setup a computer with work with caw.

Well, I did all what should be done and some ARE showing up so I did it as it should, but most f them ain't showing up.

Such as this download:

As I noticed, I ain't the only one having problems with those items not showing up but I REALLY need some more walls like that :/

The people who asks for help usually comes in two categories: those who link and describes, and tells most diligently about the issue they have... and those who complains a lot, but don't really say a thing about the issue they have. What category do you want to belong to, and who do you think gets the help they need?

"my documents/electronicarts/sims3/mods/packages folder"

That's not where I finally made brntwaffles environmental mod to work. I installed the caw framework in the caw game folders, and did as the tutorial said I should do. I might sound like a noob, but we all have to start somewhere

The Late Night items are unlocked for use in game. They are NOT enabled for CAW as Simsample states in his first sentence. You can find a method how to enable them for caw in this thread: http://modthesims.info/t/453818

The retaining walls are enabled for CAW and thus should show up if you set up your framework correctly and put them in the correct place. I am not at home so I cannot test. Tomorrow evening I'll try to find time if noone else came up with a solution. Did you try with only Simsimillian's walls (without Gelina's)?
