I've been searching for a mod that will do this since I can't seem to accomplish it with cheats. If anyone knows of a mod that will allow mounted fish or certificates to be height adjusted, I'd appreciate being pointed in the right direction.

Thanks.

There's a mod for the fish here: http://simsasylum.com/tfm/index.php...#comment-203708. There's also a mod for certificates at MATY but it's from 2011 and never got updated after LN.

Now these skill certificates can be shifted up and down the wall, and I gave them an environment score of 3 while I was at it

And while I was at it I made the WA Certificates of Partnership shiftable and with the same environment score, too:

I made them with game version 1.63 but the patch level doesn't matter because only the object properties are edited, not the game mechanics that enable obtaining them (so XMLs are not edited, only OBJDs).

Thank you both. Those mods are just what I was hoping to find. Much appreciated.
