ZBrush Usage Questions
#1
Hi Guys, I am making a creature head. And now I can not subdivide anymore. what can I do to have more details. ??? Some one told me to use more subtools...but in a head if I understand the only subtools are eyes and thoot...or maybe Iam wrong ??? I mean more details as skulpted wrinles etc.. is it normal that ONLY the head is 1.5 Gigbyte big ? Seems very big :/

please help in this crazy need of details

thanks Mario

for a head like this, there shouldn´t be a real limit in terms of detail.

you have a number of tools inside zbrush to handle this problem; i would recommend using dynamesh; duplicate your model, dynamesh it with a medium resolution, subdivide the dynamesh to about 6mio polys (this is the maximum amount of polys that seems to work fine for one (sub)tool), then use the tool>project>“project all” feature to project the details from the duplicated subtool to the newly created dynamesh.

the effect will be that you have equally distributed polygons - in contrary to your current mesh, which has an inefficient polygon distribution.

dynamesh and qremesher are amazing features that you definitely should use to get around problems like these.

you could also use a separate subtool for the teeth of the character

Judging by the picture you are showing, it doesn’t look like it should be 1.5 GB. Maybe if you are saving it as a Project file (File > Save As) I could see the file getting that big, but not if your just saving the Tool (Tool > Save As) which would result in a much smaller file size. The more subtools you have, the finer the detail you can get on each subtool. For example, in your case, you have folds in the skin that could easily hide the seams between subtools. You can split the teeth into not only one subtool, but even two subtools like ‘upper teeth’ and ‘lower teeth’ or maybe even more like maybe 4 subtools. I was the one that told you this before that the secret to getting lots of detail in ZBrush, is to have lots of subtools. I will demonstrate this with an example. Say you have a Tool that has only one subtool and you go to Subdivide it but ZBrush will only let you Subdivide it to level 5 with a total of 5 million poly’s because that is all your computer can handle. OK, there is one subtool and the most you can get is 5 million poly’s. Now, split that Tool into 5 seperate subtools. Now you can divide each subtool to 5 million poly’s which would now give you a total of 25 million poly’s as compared to just 5 million.

Thank U so much…that was a great Tip ! :slight_smile:
a beginner question: how can split a Tool into seperate subtools ???

thanks again :slight_smile:

You would have to go to your lowest subdivision level then using the Selection brushes (Ctrl+Shift) to hide sections then in ‘Tool > Polygroups’, click ‘Group Visible’ to create new polygroups at which point you could use ‘Groups Split’ in the SubTool palette to split those polygroups into seperate subtools. I’m sure if you search, you can find tutorials on this.

No problem! I have a feeling you will be making very detailed objects in no time. :):+1:
