With the last patch 1.120.140 claimed they fixed a bug where paintings by reference would go white but the issue is not fixed at all. Check the new error report thread on the EA forum here, and you can read about the real issue behind the bug here.

Temporarily disabled the filters because of that in-game bug on all paintings by reference except paintings done via my new "Paint From (existing) Photo Reference" mod. I also added a test so the interactions only show up on completed paintings.

Set Filters on Paintings by Reference

INFO
Ok, I hate the blobby paintings in the game produced by the Paint By Reference action at an easel and I know I'm not the only one that feels that way. I played around with a way to make the painting by reference not use that effect years ago to no avail. I turned my thoughts to the problem again today and realized that when paint by reference stores its images in the save game (in the clientDB.package file) it also stores a copy of the original image. A bit more playing around revealed the blobby painting is just a filter effect, similar to the ones used on the photography skill in the game.

So I figured, why not make the Set Filter command available to paintings, maybe that would clear that effect and to my surprise it really was that easy.

This simple little mod adds that Set Filter menu to all sim-created paintings. It won't do anything on a regular crafted painting, but when used on a paint by reference one it allows you to set any of the available filters quickly and easily. It will even work on a painting by reference that was created before installing the mod and the change will persist even if the mod is removed.

I also added a new interaction to allow setting the filter back to the "Painting" style should you end up deciding you liked that better.

EXTRA
The mod adds new interactions to set the filters on the paintings. These should not conflict with others mods:
