Day 8 part 2

Introduction to Zbrush Digital Tutors

Projecting Detail onto Meshes

– Zbrush can project the sculpted detail from one mesh to another. This can be useful for transferring the detail from a multi-subtool model to a single-skin model for eg 3D printing. It is also useful for transferring detail that has been previously sculpted on another model to a new model.

– Tool > Subtool > Project > ProjectAll transfers the details from any visible subtools onto the active subtool. Before projecting make sure the target mesh has enough resolution for the projected detail.

Sculpting and polypainting can be transferred from one model to another using the project tools.

– Project > Dist Slider determines how deep below the surface of the target mesh Zbrush can look for sculpted detail to project. If there are artefacts on the target model increase the distance.

– The projected detail is applied throughout the subdivision levels of the target mesh.

If the detail isn’t properly transferred try increasing the distance Zbrush looks for detail.

Introduction to Zbrush Digital Tutors

Remeshing Geometry

– Zbrush contains tools for creating a new unified mesh from individual parts. Tool > Subtool > Remesh > Remesh all creates a new mesh from everything in the current subtool. Symmetry options can be used to make symmetrical models from asymmetrical subtools.

Subtool > Remesh all can be used to create a single mesh form a group of objects.

– Objects within the subtool can be set as additive or subtractive objects for boolean operations.

– The Res slider under Remesh determines the resolution of the new geometry.

Subtools can be used to add or subtract from the new mesh.

– Tool > Geometry > ZRemesher contains tools for changing the resolution of a mesh or improving the flow of polygons in the geometry, for example making sure the polygon flow on a face follows muscle groups.

– ZRemesher > Target Polygons Count determines how many thousand polygons are in the new mesh. Press ZRemesher to complete the action.

– Use the ZRemesherGuides Brush from the brush palette to lay guidelines for the new mesh. Use the Zremesher > Curve Strength slider to determine how closely the guidelines are followed.

Zremesher can be used to change the resolution and polygon flow of a mesh.
