A mix of both. We do a lot of baking these days, but sometimes it still makes sense to start from a photo source, tweak it and generate normals that are more than good enough.Regarding normal maps and AO, do you guys use high poly sculpted assets and then bake it down to the low res one or do you use stuff like xNormal/NDO to generate a normal map from reference photographs?
For the duck, we used the roasting procedure.
