Can’ delete subD level. help please, i need delete to a level to extrar my displacement at the right level.
how can i recover this?
Unless something has changed in ZBrush 3 you still compare the current subdivision level to the highest subdivision level when creating a displacement or normal map. There is no need to delete subdivision levels, simply go to the subdivision level you want as your base mesh.
After adding a Geometry HD subdivision level you cannot add or remove from the standard subdivision levels. Pressing Tool > Clone will clone your current tool but without the Geometry HD subdivision(s), you can then add or remove subdiv levels, but will have lost the HD Geometry.
WOW Thank you 
I will give that a try
you can easily jump back to the normal sub-d´s. just go back to level 1 in the hd geometry menu.
i Try bringing the divideHD to 1 but nothing.
How does the clone tool works how can i merge the old one with the new one???
just change the sculpthd sub-d to 1. of course with the old model not with the cloned one. after that you can change the standard sub-d´s so no need for deleting them.
you cant transfer the hd stuff to your cloned model. (afaik)
So this is what i am doing:
- Import the original model with the sculptHD
- go to level 1 in the sculptHD
- go tools and press clone
