Before you convert U3D to AVIF

U3D describes geometry rather than pixels, so it has no inherent resolution. The conversion renders it at whatever size you choose, and that choice is final: enlarging the AVIF afterwards will not recover the sharpness. Set the output dimensions or DPI before converting, not after.
