Not everyone cares for Substance Designer (which isn’t on Android anyway) and sometimes it’s just more joy to sculpt meshes for tiling PBR textures. I am not sure if Nomad already offers something like that, but if it doesn’t, would it be possible to implement such functionality ?
Here are some examples of how tiling sculpting is done in ZBrush:
Wrap mode is pretty poor way to do tileable textures in zbrush. It gets very laggy quickly. Way better way is array mesh that´s basically instancing. As far as i remember Stephane had instancing in his roadmap. So eventually that would also fill this request including other purposes for instancing.
Perhaps (I never used ZBrush). Although, I tried tiling sculpting in Blender and didn’t have any issues.
