Perhaps the most crucial feature for avatars is the BlendShape (Morph Target) system. VRM supports standard facial expressions like joy, anger, sadness, surprise, and visemes for lip-sync (A, I, U, E, O). This is necessary for making the character feel alive in VTuber software or social VR [8†L15-L17].

For the highest quality conversion, step away from automatic browser tools and use specialized software. Best Used For Why It’s Better Full control and manual cleanup
A "better" conversion is one that respects the technical requirements of the destination format. It moves beyond one-click solutions by addressing the rigging hierarchy, standardizing facial expressions, and implementing physics. For creators looking to produce professional-grade avatars, the conversion is not a post-processing step, but a distinct phase of development requiring manual refinement to ensure the digital persona performs as intended in virtual spaces.
