Mesh only visible through windows

Hi. We would need to see the blend and package files to know for sure

When making content for ts4, you need to make yours be as close to a similar maxis object as possible. Also, when you resize, move or rotate something, do this in Edit mode.
- clone paintWallQA2x1x2 , export the blend, open it;
- File - Append, choose the blend you gave me, then Object, then ThePictureFrame only, append it;
- switch to orthographic ( NUM5) side (NUM3) view;
- select ThePictureFrame, press G Y, align it with the maxis frame. This is the reason why it is sinking into the wall;
- with this object still selected, add a new vertex group, double-click to rename it to transformBone;
- switch to edit mode, select everything with A, assign the painting to transformBone;

- back to Object mode, Object - apply - all transforms to delta;
- now that transforms are right, re-unwrap your mesh in uv_0, right now uvs are shrunk and textures would be as well. You can delete uv_1, objects dont need it;
- delete the original painting;
- select the shadow plane behind it, switch to Edit mode, resize and move it to fit your painting. If you want to remove a meshgroup, hide it withing an object, dont move it to a random place. And, again, do it in Edit mode;
- save, import back into paintWallQA2x1x2

That worked out really well thank you. One more question I am creating couch pillows but I am not sure what base game object would be close to that to clone.
