OK I know this is somewhat lazy but i'm still trying to figure out how to mesh properly in the sims 4.
This is just a recolor from an original in-game painting but as it is locked it will appear as a new object (price: 150). Since this is a pretty basic frame i'll probably use it for more recolors from now on so I recommend you to download it and stay tuned until I update it.
Last but not least I'll be glad to get some feedback (not in "this is amazing" way, just to know if it works correctly.
Ahead some pics and the download link & thx
