Merge SubTools and Weld
From ZBrush Info
A new function has been added to the SubTools menu: Merge Visible SubTools. It allows you to combine several SubTools to create a new ZTool which will retain all the current polygroups and as far as possible, the Subdivision levels from previous SubTools.
The associated Weld option will weld all overlapping vertices which are at the border of two SubTools. This allows you to sculpt over multiple SubTools without any seam spread. Tool >> SubTool >> GrpSplit will split the current merged tool back to the various SubTools after you have sculpted your changes. Your vertex points must match in order for a true weld to take place.
Merging several SubTools into one new ZTool: The Merge visible option, under the SubTool list.
- Load a ZTool with several SubTools.
- Hide the unwanted SubTools.
- Check the Subdivision level of all the SubTools.
- Select the main SubTool. If other SubTools have a higher subdivision level, those
levels won’t be kept. For example one tool has 4 levels but the other SubTool has 5 levels. You will lose the fifth level when merged.
- Click on the Tool >> SubTool >> Merge Visible button to create a new SubTool.
- In the Tool palette, choose the new ZTool to replace the previous ZTool with all
its SubTools.
Notes :
- If all the visible SubTools have the same Subdivision level count before the operation, the created
new ZTool will keep these subdivision levels.
- If all the visible SubTools have different Subdivision levels before the operation, the created
new ZTool will keep the maximum Subdivision level possible, but may delete lower or highest levels, depending on which SubTool was selected before the operation. Welding only affects points that share identical positions. This feature cannot be used to perform Boolean operations.
