Project Undo History
Go back in time to set a restore point and project this information back into the model
ZBrush remembers the sculpted and painted details within the Undo History timeline. Project Undo History gives you the ability to go back in time to set a restore point and project this information back into the model. With this feature you can choose any point in the timeline to project back onto the model.
While making design changes for a project, this feature makes it incredibly easy to restore previous iterations of your design without the need to resculpt or repaint.
How Project Undo History Works
After building up the Undo History timeline for a model, to project former details back into the present point in time you must first set a time projection point. This is done by moving the timeline slider to a point that contains the details that you wish to restore. You then set the point by ctrl+clicking on that timeline point.
Once a source projection timeline point has been stored, the timeline must be set to the desired destination point. Do this by clicking anywhere along the timeline or clicking and dragging the orange cursor hash mark to its destination.
When the projection destination has been set, click SubTool >> Project >> Project Undo History to process and apply the projection history point.
Project Undo History in Action
1. This example shows a DynaMesh model with undo history, and design changes made across the history timeline.
2. This example shows the present point in the undo history timeline where details have been changed to same highlighted area of the model.
3. To Project History from the details highlighted in image 1, do the following:
Click the orange timeline mark, click the desired undo history timeline point, then Ctrl+click on that timeline point to store it for projection.
4. Drag the orange timeline mark back to the most recent undo history point where changes exist. This will be the version of the model that receives the projected details.
5. Click SubTool >> Project >> Project History.
6. At the most recent timeline point, the projection is now applied.
7. Click Undo (ctrl+z) to remove the projection that you just completed. Now draw a mask over the surface for projection and then invert the mask.
8. Click Undo (ctrl+z) to remove the projection that you just completed. Now draw a mask over the surface for projection and then invert the mask.
Project History/Project All Functions
This switch tells Project History to process geometry projections from different points in the undo history timeline.
This switch tells Project History to process vertex color (PolyPaint) projections from different points in the undo history timeline.
This switch enables projections from the source mesh to the farthest point of the target.
