dσd (x) : R3 → E,P,W.

In a slight abuse of notation we reuse E, P, and W from
FLAME – please note that these denote continuous implicit
ﬁelds from here on. For each canonical point xc, the trans-
formed location xd := wσd (xc) is:
xd = LBS(xc+BP (θ;P)+BE(ψ;E), J(ψ), θ,W), (5)

where J is the joint regressor from FLAME. This deﬁnes
the forward mapping from canonical points xc to deformed
locations xd. We detail the computation of the inverse map-
ping from deformed to canonical space in Sec. 3.3.
Normal-conditioned texture. We leverage a texture MLP
cσc to map each location in the canonical space to an RGB
color value. To account for non-uniform lighting effects,
we additionally condition the texture network on the nor-
mal direction of the deformed shape. For implicit surfaces,
the normal direction can be calculated as the normalized
gradient of the occupancy ﬁeld w.r.t. the 3D location. In our
case, the gradient of the deformed shape is given by:

∂fσf (xc)

∂fσf (xc)
