I’m confused.
I have two subtools that I am trying to merge. I have subdived both with a range from 1 to 6. However when I merge with both subtools at the highest subdivision level (6) I end up with four subdivision levels on my merged subtool.
The first two subdivision levels have been deleted, so I don’t have the low polycount mesh I had on the seperate subtools.
I have followed this procedure on other subtools and not had any issues.
Can anyone give me some clues?
Thanks
This is just a random guess. but perhaps you should merge the subtools at their lowest subdivision level. then the subdivide after they are merged. this will allow you to keep the low poly level. when you merge the 2 subtools, zbrush forgets the lower levels and creates the tools as one whole tool, starting at what is level 1 subdivision even tho you had a much higher SD of the 2 tools separately.
Hope this helps.
Thanks Gridlost
I’ve all ready tried this. The problem is, after subdividing the merged subtool I lose the detail that I have all ready sculpted on the two seperate subtools.
I just tried an experiment:
Loaded subtool (sphere). Appended subtool (Cylinder).
Divided both subtools up to 5 subdivision levels.
Merged.
The result was that the subtool divisions were all deleted on the merged subtool.
Why am I getting conflicting results?
I just had a look at a tutorial where the tutor merged two subtools but mentioned that before merging to make sure they had the same subdivision levels. His merged subtool still kept the subdivision levels.
Now I’m even more confused and convinced I’m doing something wrong.
Any help would be gratefully received,
Thanks
good to hear. I miss little details like that all the time in videos.

Are you experiencing the same issue or is it just me?
I just loaded two subtools I’d created some time ago. I pushed them both up to six subdivisions, merged and guess what. The merged subtool kept all six subdivisions.
This is now driving me crazy…
The only option I may have is to re-create the subtools I am having problems with, which means hours of repeating something I’ve all ready done.
I’m sorry man, I’m still pretty much a noob with Zbrush. I didn’t mean to lead you on.
I do recall the tutorial you are talking about. I do believe you are doing it right. I wonder tho… the Zbrush version in the video, is it 3.1 or 3.5? Also what version are you using? Are you on a Mac? These things may lead to your core issue. perhaps there was a change made in 3.5 in how this merge process is handled.
Have you tried doing a google search on this?
Yeah, I’ve done a google search and a ZB Central search. Can’t find what I’m looking for.
I’m running 3.2 on Mac. But as I mentioned earlier, it works on some subtools and not on others. This is why I am convinced I must be doing something in my workflow that ZBrush doesn’t like.
It just doesn’t make any sense and I can’t understand why no one else seems to be having the same problem, hence only you seem to be showing any interest in this post.
I’ve pretty much cracked ZBrush and am getting close to completing my second project, which is going really well, that is until I came across this issue, which has really thrown a spanner in the works.
Thanks for your support Gridlost.
I just thought I’d update this thread after discovering one reason for the sub tools merging without the polycount I originally set up.
Whilst retopologising a new sub tool you need to ensure the “skin thickness” has either a negative or positive setting.
After “make adaptive skin” the sub tool will merge, keeping the subdivision levels.
If the “skin thickness” is ignored, when merging with another sub tool the polycount structure is destroyed, preventing you from stepping down subdivision levels.
I think the other reason is as mentioned above - trying to merge subtools that have a combined polycount which your system can’t handle.
