Where I could composite vector shapes with feathered edges and bitmap fill of albedo textures , then easily replace the fill with normal map or spec for export . Doing pixel grid snap , no sub-pixel blurring. And a spline/brush based scattering those bitmap filled shapes or deforming alternating stripes along the spline. Re-sead-able . Also with ability to quickly switch the atlas.
I don't know a single one for PC currently after death of Expression.
Affinity couldn't even keep bitmap fill in same position after re-linking.
Maybe something like that exists in a realm of tablet apps ? Would even buy Apple tablet again for this.
