Because of the DynaMesh process, the Insert brush has become a major player in your ZBrush arsenal of features. Now that it also allows you to actually replace portions of a model, several new enhancements have been made.
- In addition to inserting a mesh as a negative, holding ALT while inserting a model can also stretch it perpendicularly to the insertion. The mesh is inserted within the surface that it is being drawn upon.
Note: If after using the ALT modifier for drawing one object you continue to draw insertions of the same item, these additional insertions will keep the same transformation.
- Press the CTRL key while inserting the model to respect the original inserted mesh proportions (1:1 ratio).
- Press the Shift key while inserting the model to constrain the insert mesh orientation to the closest world axis plane of the model, based on your point of view.
Note: If you need to revert to the original size, just press the CTRL key while inserting the mesh.
- The Z Intensity setting will control the height of the inserted mesh. Keeping Z Intensity at 100 will maintain original height orientation of the mesh. If Z Intensity is set below 100 then ZBrush will reduce the height of the inserted mesh based on this value.
- A Projection Strength slider has been added in the Brush >> Modifiers sub-palette. When using a high value, the inserted mesh will conform itself to the underlying surface. Using a low value will preserve the original shape
Notes: If your inserted mesh gives unexpected results, check if the projection strength slider and try modifying its value.
Don’t forget that pressing the Spacebar while inserting a mesh will let you move it across the surface of your model to refine its position.
