Sadly there is no material /texture software that I would consider convenient. All them are monstrously terrible IMO. You can just tolerate one while other feels intolerable. 3d coat had been tolerable for some time but then stopped to be such . I switched to Painter and hated it no less. All it's non-destructiveness is…
It's not that good, unless it's taken some huge strides since last time I saw it. The voxel sculpting is really convenient, but lacks clarity, unless you go high res in which case you'd have similar problems to just starting at a high dynamesh res. Means you get a similar feeling at times, but you don't get the convenience…
