I'm not exactly sure how to explain this but there's this decoration object that i downloaded that i'm trying to put on an OSMP. it was a 2 tiled object. I changed the number of tiles the object uses with SimPe and this tutorial: http://modthesims.info/t/242079

but im still not able to paste it on an OSMP, can someone please tell me what I have to modify in SimPE so I can put it on an osmp?
please help.
