Modelling Guidance needed

#1

Hello I’m an art student in training and I have just started getting my head around ZBrush
but before I realized that ZBrush is the new base modelling tool I had already modelled a base mesh in Maya. The problem i’m faced with at the moment is that i have been trying to sculpt around this base mesh but it is laggy and the brushes don’t behave correctly when i use dynamesh it would add more subdivisions while taking the shape of my original maya low poly model,. Is there any way i can make my current model more sculpt friendly while keeping the topography? or do i have to scramble it and start over? thank you for taking time to stop by if you have any other workflow tips or critique it would be greatly appreciated.

By looking at your Active points, there shouldnt be a reason for it to be laggy. I can go up to 10 million active points on my computer and still be able to sculpt… Either you may need a faster computer or try to trouble shoot the problem with process of elimination. Hard to know whats messing up unless I open up the scene myself.
Dynamesh will get rid of your clean topology because dynamesh is meant to keep adding more topology as you keep pushing and pulling.
