Well, Roblox removed Anthro files, and added R15 V2. But R15 V2 was newer version of old R15. You can see R15 V2 shown on folder. But the flaws of R15 V2 default model was reducing blending elbows and knees, unless you set to max to bring it back the blending elbows and knees. In fact, New R15 model doesn't blend anymore. :\

Here's a problem about new R15 model. Plutonem just noticed how new R15 model doesn't seems to be blendable on DevForum. It's just reducing blends.
