Video Tutorial: How to Merge Geometry Using Dynamesh
-
there are many ways to create mesh within ZBrush
-
one method is to use primitives or smaller pieces of geometry to create the parts of an overall figure
-
it's possible to unify those parts into a single mesh by using merge and by coverting the geometry to DynaMesh

Video Tutorial: How to Make Holes in Dynamesh using IMM Primitives
Note: This can be useful when creating hard surface models such as props and furniture.
This Video covers:
-
converting a primitive to a polymesh 3D
-
converting an object to dynamesh
-
adjusting the z intensity of the smooth function
-
using IMM primitives in a subtractive way (use hotkey alt)
-
using display properties to see all sides of an object
-
using the 3D Gizmo to adjust the position and scale of an IMM
-
clearing a mask
-
using dynamesh sub to subtract the IMM from the main subtool

Video Tutorial: Drapery Timelapse Video
Steps for sash/ draping cloth:
-
use a wider part of the body to perform an extraction (mask with lasso mask & extract) in order to get the mesh for the sash - chest and shoulder
-
zremesh the sash subtool to get better topology
-
divide the subtool to get more polygons
-
move the sash down onto the arm
-
use masking and move brush to manipulate the mesh to look like fabric
-
use dam standard to create distinct creases
-
use clay buildup in order to create or accentuate your folds
-
use trim lasso to cut away any mesh that you don't want - I used trim to get rid of some of the fabric under the arm
-
append a plane by going into geometry > append > select a plane
-
go to tool > display properties > double to see both side of the plane
-
use 3D Gizmo to scale and move the plane to look like the hanging cloth
-
use masking and move brush to adjust the fabric as needed
-
merge the main part of the sash and the hanging part by using the arrows in geometry to get the two subtools next to one another
-
merge down so that the two subtools become one
-
if you do this and still need to make adjustments on one particular part - use masking or use the brush called move topological to move the two parts independently of one another
-
if you go to line fill poly and click it - you will see that the two parts are separate polygroups even though they are the same subtool
-
if you have any issues using the move topological brush to adjust the polygroups > go to brush > brush modifiers and move the slider to 100
-
if you want to, you can dynamesh the subtools so that both parts unite into one mesh (but it's not really necessary)
-
attached is a time lapse video of what I did to make a sash
-
in the video, I did it really quickly using a mouse - if you use a tablet and take your time, you will get even better results
-
If you wanted to create a sash that could be unfolded and or/ possibly animated - you would begin with a plane, double it in display properties, scale it and sculpt, move it into place on the figure model, then use masking with blur mask, followed by move and rotate on 3D Gizmo to wrap the fabric around the body and/or arm.
Video Tutorial: Review of Basic Polypainting Techniques
Note: Use the C key for color sampling within Zbrush. This function is useful if you need to replicate a color you have already used on your model.
Note: Using using color > fill object can fill the object temporarily, but don't count on it to be that way the next time you open the file. A better method is to paint materials onto the mesh using polypainting.
Review of the following:
-
initiating the polypainting function
-
strokes
-
using drag rect
-
polypainting with alphas
-
polypainting with textures
-
assignment of materials
-

-

Video Tutorial: Method 1 - Quick BPR Turn Around Image
Method 1 for lower poly sculpts
1. Document > double canvas size to allow for greater resolution of the rendered image and use zoom doc to make sure that it fits in canvas
2. In document make sure that the range is 0 to get rid of any gradation
3. Merge subtools
4. Position model in front view
5. Duplicate and move the model copy into another position like 3 quarter view using 3D gizmo
(make sure that symmetry is off> hit hotkey x or model will tear apart)
6. Make another duplicate of the original front view model
7. Move the model copy into another position like side view

various turnarounds can be looped together
Video Tutorial: Deleting Curves in ZBrush
-
stroke> curve functions > delete
Video Tutorial: Creating Drapery/ Skirt in ZBrush
(Method - spheres and curves)
-
open sphere 3D using simple brush icon
-
make polymesh 3D (button towards the top of tool panel)
-
divide it in geometry panel or hit command d
-
delete lower subdivisions in geometry panel
-
duplicate sphere
-
select new subtool and move/ scale using 3D gizmo
-
go to first subtool
-
make sure that slice curve is selected or you will get selection when you hit control shift
-
use slice curve to slice the bottom part
-
turn on line try fill to see the new polygroup
-
hit control shift and tap on the top part of the sphere to choose it
-
go to geometry > modify topology > delete hidden
-
go to second subtool
-
use mask pen or mask lasso to create the shape for the botto
-
if you hit control, mask pen will be selected by default
-
to select another type of masking, hit control and click on the brush icon - the other choices will emerge (choose the one you prefer, I tend to use mask lasso)
-
now hen you hit control, it will automatically select the type of masking you chose
-
you may want to turn off symmetry
-
mask out the area for the bottom on the second sphere
-
if you accidentally select a part that you don’t want, use control alt to delete parts of the mask
-
hit control w to use the mask to create a polygroup
-
turn on line fill poly to see the new polygroup
-
go to geometry > edge loop > panel loop for a nice edge
-
hit control shift and select the top part of the sphere
-
go to geometry > modify topology > delete hidden
-
merge the two subtools by selecting the upper subtool and clicking merge down
-
you may not be able to see both side o f the obkjects - go to tool panel > display properties and select double
-
go to the brush panel and choose the curve bridge brush
-
drag access the surface of the upper object and hit shift to select the edge
-
you will see that the edge is selected
-
do the same on the bottom object
-
a curve bridge will be created between the two
-
hit control shift and click on the drapery
-
go to geometry > modify topology > delete hidden
-
to eliminate the curves, go to > stroke at top of screen > curve modifiers > delete
-
you my want to use Zremesher on your drapery to get even better topology
-
you can divide it and sculpt on it as you would any other mesh
-
for example, you may want to use clay buildup and dam standard to create more volume as well as creases
