Since some weeks, all my NPCs don’t save their new sizes. When I restart Roblox Studio, it reset NPC basic size…
this picture is from an NPC I animated before to close my roblox studio , he was bigger than before, and this screen has from when I opened again Roblox Studio, someone can help me ?
Did you just size it up with the re-size tool or did you edit the values.
This might be the problem if you didn’t edit these. I think this happens with r15 and rthro characters.
I never touched at this, in explorer, I use “Scale” for the NPC’ size
That might be the problem, I don’t really know though. maybe try it out.
Sure I’m going to try , just I finish to animate something on a NPC
okay so you mean, I need to change the original size ? May I delete it ? 
I Don’t really know if that even effects it. It was just a thought, try deleting it. You’d probably still need to resize it back to normal after.
AFter I deleted all original sizes 
Also I retried in changing all original sizes in copying parts’ size in original size and I got the same thing than on this picture
Oh, I’m sorry. I wish you luck in fixing this problem. I’m not sure what it would be.
Really Weird… Roblox shoulds remove the “OriginalSize”
The issue might be the scaling values in the humanoid. Try editing those. These are the values I am referring to:
These values are what influence the size of body parts on RThro and R15 rigs. I believe
BodyProportionScale BodyTypeScale are the RThro ones, so you might want ot keep them set to the minimum if you want simple R15 scaling, or increase them if you want RThro scaling. The other values such as width, height, depth and head apply to both R15 and RThro if I remember correctly.
