Zbrush wont let me subdivide my mesh!

ZBrush Usage Questions
#1

Facing yet another problem with my model at the moment, for some reason I just cant add anymore geometry to my mesh to add fine details such as finger nails etc. I have made models in the past that have had extremely high resolutions and have run fine on my PC, however, when I try and divide this particular model I get the warning message :"NOTE: Subdividing the current mesh will produce a mesh with polygons count larger than specified in the PREFERENCES:MEM options. It doesnt make sense because the polygons are very prominent in areas such as the fingers (the rest of the model looks fairly high res however which is strange) my PC is very high spec and should easily be able to up the resolution.

I should note that the model has been dynameshed a few times (not sure if it matters or not) this is the last problem im facing before I pose out the model so any help is enormously appreciated.

you probably need to retopo the mesh so you don’t have a uniform mesh resolution, which is what dynamesh does.
A qRemesher with some control curves should do the trick. You can also break your mesh into subtools to allow you a higher resolution.

Zbrush is probably set at 22million per subtool for you. You shouldn’t up this number as Zbrush will become unstable.
What are your settings in preferences.mem?

I just tried Qremesher, followed a tutorial exactly I found on youtube, duplicating the model, deleting lower subDs, masking out portions that require higher detail etc, but when I click to Qremesh the mesh I run into problems, first of all it will be stuck at initializing Qremesher for asbout 2 - 3 minutes. When the loading bar does start to progress ill only get a an inch across before it gives me an error, ive tried it over and over and every time I get errors.

As for the preferences.mem im not sure how to check that, but it should be set to the default.

that is probably your problem…memory I mean.

the default for Zbrush is 256 MB is allocated to it.
go into your preferences.mem and up your memory allocation to 4096 (if you have 6 or more GBs of RAM).

After telling Zbrush to use 4 GBs of RAM you should be able to run qRemesher.
Also, what is your processor. I believe qRemesher uses it, but I could be wrong.
