Spa Day Magazines at Home

Thanks. Oh yeah, also can you also point me to the mod you are using that makes the magazine available in the catalog?

You may wish to pass it on to the bug team, or whichever unit it is that deals with bugs.
The following tunings, for regular books that Sims are supposed to read, incorrectly use the "book" value instead of the "bookThin" value;

bookThin_Charisma_Advanced
bookThin_Cooking Advanced
bookThinRWCareerIntMag_01
bookThinRWCareerAstrMag_01
book_Herbalism_Beginner
book_Violin_Beginner
book_VideoGaming_Beginner
book_Programming_Beginner
book_Painting_Beginner
book_Piano_Beginner
book_RocketScience_Beginner
book_Writing_Beginner
book_Guiter_Beginner
book_fun_NoRetailDisplay

Hopefully they can be corrected and included in a patch some time in the near future.

Hey there, I don't really know off the top of my head. My expectation is that they are playing different animations, and that is causing the difference. If you can post screenshots of what the magazine looks like in both scenarios I can investigate a bit more. Thanks.

Okay. The first picture shows the stretching and hand position when holding the book, and the second shows it while reading.
The texture is different on the magazine my playable Sim is holding as that one was designed by a community member.
(It was very difficult to get a shot of the spa worker just holding the book closed as they grab it from and put it back into their inventories/hammer space very quickly unlike active Sims who place them on the floor.)

The magazine was unlocked and recoloured by ajOya which can be found here> http://bsimth.tumblr.com/post/132315239962/8-readable-magazines-martines-b-day
I also downloaded some extra recolours by Jorgha-Haq from here> http://jorgha-haq.tumblr.com/post/144403012387/this-started-out-as-a-small-recolour-project-for which require ajOya's version to work. (If you don't have them these recolours can't be placed as they have no footprint resource.)

Okay. So another CC modder has released some MORE magazines that can be read by regular Sims. They seem to really be THE item of CC to have right now.
Thanks to this I have managed to solve the issue of the books stretching when being read. The ones that stretch are using tuning that classes them as "book". The ones that don't stretch are using tuning that classes them as "bookThin."
The only issue that remains now though it the Sims' hand pose when holding a closed magazine as that still isn't right with any of the CC magazines I have found.

They are the last item on the Files tab list.

ETA: I just discovered some of the base game skill books that are thin also suffer from the wrong holding position. The level 1 fishing skill book, for example, is held correctly by Sims but the "How to be a socialite" Charisma skill book isn't.

ETA2: Mystery SOLVED! (I think)
The tuning for the thin books that are held incorrectly basically have the wrong carryObject value set. I realised changing "book" to "bookThin" under object TYPE would stop the stretching but didn't pick up on the fact that in the line above, the carryObject sets what animation to use and that was also set to "book" instead of "bookThin". I just made an override of the socialite book tuning to make the required change and my Sims now hold the book exactly as they should.

OK great, glad you got it figured out - nice sleuthing.
