The 3D standard for BAYC likely would be set to show case interoperability. We would recommend wait for more clarity to work on it to minimize extra cost and time spent. Not following the body size standard in 2D, Voxel, 3D would mean spending extra labour and time to remake wearables and emotes.
The submission fee is very small portion of income for the DAO compared to any ticket or land sales for Decentraland. Great content drives audience. The better question to think about what wearables would echo with the audience? How can we line up these brands for upcoming trips for The Otherside?
