Merging subtools with UV problem.

ZBrush Usage Questions
#1

I was wondering if someone could point me in the right direction with an issue i am having.

I have two subtools, both have uv’s. One of the subtools is made up of several polygroups, the other is a single polygroup. They both have 5 subdivisions. I want to merge the subtools and keep the subdivisions. When I merge visible with the UV button on, I get a merged subtool, but I lose my lowest subdivision level (merged with both subtoold at subdiv 5) I can make a clone and flatten it in UV master, rearrange the islands, unflatten, copy UVs and paste on the original merged tool, but when I check the UV (morph UV - UV sub pallet) they model seems to merge into one point. I have done this many times and am not sure what i am doing differently this time. First I was wondering, why am I losing my lowest subdiv level, and second, why cant I paste the new UV onto the merged model?

Any help would be appreciated.

Thx

Do you get any errors when you try to reconstruct the lower levels?

Hi Cryrid

Thx for the reply.

The reconstruct subdiv button is greyed out! I usually preserve all the original subdiv levels when I merge in this way. Not sure why the lowest one is being lost in the first place.
