Day 3 results

Some very useful new information regarding setting up reference images, this will make sculpting form sketches much easier, as well as knowing how to create reference images for eg colour swatches or illustrations. Learning the different methods of repositioning meshes has given me a better grounding in how to set up multi-part models. Hopefully later in the tutorials they will cover how to move an object yet still sculpt with symmetry.

Remembering to switch off the Smt modifier when subdividing will be essential when it comes to hard edge modeling, which I am keen to do.

Day 3 part 2

Introduction to Zbrush Digital Tutors

Transforming 3D objects

– The Tool > Deformation palette contains sliders for modifying many aspects of a mesh:

– Offset  in combination with the X Y Z buttons allow for repositioning a mesh on the canvas.

– Rotate in combination with the X Y Z buttons allow for rotating a mesh aorund different axes on the canvas.

– Scale in combination with the X Y Z buttons allow for uniform or non-uniform resizing of a mesh.

Resym modifiers contain options for moving, rotating and resizing meshes

– Note that the sliders only refer to the degree of change in that action ie if a mesh is rotated the slider will reset to 0 and will have no memory of that mesh’s original position.

– the Move, Scale and Rotate buttons on the top shelf can also be used by using the transpose tool.

– The transpose tool is a gumball with many points to affect the mesh. Tool tips will appear in the status line when they’re hovered over. Options include duplicating, clipping, skewing / stretching and duplicating meshes when combined with RMB and Ctrl.

The Transpose tool combined with Move allows for several affects including clipping, stretching, inflating and duplicating meshes.

– Tool > Geometry > Position / Size also contains sliders for manipulating the mesh. Unlike the other options these do remember where the mesh was before modifying it, allowing for returning it to its original position.

The geometry size and position sliders are relative to the mesh’s original position so it can be easily restored to its starting point.

Setting up reference images

– These steps are specific to this model:

– draw a cylinder primitive

-in the Initialize palette set X and Y size to 20

– in the Deformation palette rotate by 90 degrees in the X axis

– subdivide several time

– Make PolyMesh3D

Preparing the start of the model.

– under the Draw Menu there is a palette specifically for grids and reference maps. Options include which faces to assign Maps to (Front-Back, Left-Right, Up-Down), and an option for using one Map for both planes (one).

buttons for assigning reference images to different planes around the model.

– Map1 / Map2 brings up the texture palette to select an image.

– If the image you wish to use isn’t in the texture palette, go to Texture > Import and the images will be available next time you click on Map1 / Map2. Other options are enabled once a Map is loaded.

Once an image is imported it can be applied to any of the reference map buttons.

– Draw > Snap > Snap to Mesh snaps the reference map to the size of the mesh on the canvas.

Snap to Mesh makes the reference image the size of the mesh on the canvas.

– Draw > (F-B/U-D/L-R) > Adjust allows for changing the reference map’s colour, contrast and cropping.

reference maps can be cropped and adjusted within Zbrush.

– To make the reference map visible through the mesh use Draw > Fill Mode 1 / 2 / 3, or the Front button.

Use the fill mode slider to change how visible the reference map is during sculpting.

– once reference maps have been set they can be all switched off at the same time using the floor button on the right shelf.

– Reference images can be created from a model using Draw > Snapshot to Grid, which creates a texture map for each of the six planes.

Use the Snapshot to Grid button to create reference images from a 3D model.

Introduction to Zbrush Digital Tutors

Setting display options.

– Draw includes several palettes relating to the canvas view.

The draw palettes lets you change viewport and floor settings.

– Transform > Transp makes every subtool except the active tool transparent.

Use the transparency button to make subtools except the active one transparent.

– Transform > Ghost makes the transparent subtools more visible.

– Transform > Xpose (Shift + X) button explodes the model until pressed again, allowing you to see what subtools the model is made of.

Xpose explodes the model into its component subtools.

– some Tools eg Xpose feature a small X Y Z that can be turned on and off, affecting which axes the tool  works on.

– the Frame (F) button centres the canvas on the 3D model.

The frame button focuses the canvas on the model.

– the See Through slider makes the whole Zbrush interface transparent, allowing you to eg load up an image in a search engine that can be seen as reference while sculpting.

The Zbrush interface can be made transparent to see reference images on the desktop.
