Masking offers similar problems when you’re trying to paint a mask on just one lip and not both.įigure 3.14 This solider was created by Fabian Loing using some unique masking techniques.

For the generic head, we need to import it into the program. ![]() Previously we were selecting ZBrush primitives from the Tool menu. NOTE: To change the color of the newly created PolyGroup, keep hitting on GroupVisible and the colors will cycle until you find one you like!ĥ) Shift + Ctrl + Click on the empty canvas to reveal the rest of the mesh…Ħ) Select the newly created PolyGroup by Shift + Ctrl + Click on the PolyGroup.To begin, we’ll import the base geometry into ZBrush as a tool. WARNING! If you can only see one side of the mesh, go to Tool / Display Properties / Double…Ģ) Use Shift + Ctrl + X to GROW the selection: the PolyFaces that were hidden near the edges will re-appear…ģ) To SHRINK the selection, use Shift + Ctrl + S.Ĥ) Once you have all the PolyFaces you want to group, go to Tool / PolyGroups / GroupVisible… This technique is similarr to Maya’s Grow Selection, and it even has its key-shortcuts! What we are going to use this technique is to Group different PolyFaces to a finger, so we can eventually moves the different digits to form a pose…ġ) Use Shift + Ctrl + to select (thus, hiding the rest of the mesh,) a starting point… Sometimes we want to group by visibility and using the Shift + Ctrl keys and selection Polyfaces to do that, well… it can be a pain.
