Background: I was trying to learn how to mod sims 4 by creating a children can paint mod, I got it working to the point that children can use the easle and paint something through tuning XMLs, but as expected, they have a stretched adult animation. So I tried tweaking the paint animations in Blender to remove the stretching at least, but I'm not sure how to import it back to a package file so that the tweaked animation is played instead of the stretchy ones.

For example I started with these animation files by exporting them through S4S:
* a2o_easel_paint_boldStroke_large_x
* a2o_easel_paint_boldStroke_x
...and more

removed the stretching on blender and replaced filename so that"a2o" is now "c2o" and imported them into a new clip pack on Sims 4 Studio. But it seems like it changed the clipName to something new with my creator name on it. I tried editing the clipName using the Warehouse/ Data tab but it keeps reverting to something like creatorName:PosePack_202101310044116131_set_1 even after saving it.

First of all, do you think is the clipName the issue, and if so is there a way to modify the clipName? Or is there something else I should do to get this animation override working?

I'd appreciate any advice.

You need to remove the snippet that's for poseplayer from the file and it will stop reverting. It probably is a clipname issue since the game looks for the c2o, etc. to know to use a different animation.

Thanks! Got it working now, seems like I also needed to change the Instance value to be the new FNV64 hash of the c2o animation names.
