+# AvatarScaleMod
+ 
+Proof of concept mod to add Avatar Scaling to any avatar. This is local-only, but I may toy with using Mod Network.
+
+Legit threw this together in three hours. ChilloutVR handles all the hard stuff already with its existing animation-clip-based Avatar Scaling.
+
+https://github.com/NotAKidOnSteam/NAK_CVR_Mods/assets/37721153/7405cef5-fd68-4103-8c18-b3164029eab1
+
+## Notes:
+* Constraint scaling partially conflicts with avatars run through my [Avatar Scale Tool](https://github.com/NotAKidOnSteam/AvatarScaleTool).
+* This is local-only, at least unless I bother with Mod Network.
+* The entire thing is pretty messy and I am unsure of the performance impact, especially with scaling all lights, audio, & constraints.
