Every time I am trying to project subtools in a single volume I get some spikes in deep areas, holes etc. It never goes right. That’s the reason I pretty much don’t use the whole “modelling free then project everything” method and all the new dynamesh/shadow box Zbrush features and use the old way: do/unwrap everything in 3d soft and use Zbrush for some detailing only.
Perhaps it’s just impossible to get rid of spikes completely in problem areas or am I missing something?
