Restoring symmetry

From: ZBrush 4 Essential Training

Video: Restoring symmetry

Sometimes you may be working on a model that you intend to be symmetrical, but you forgot to turn on symmetrical sculpting beforehand. Now, you've put all this work into one side and now you are dreading having to redo all that work. Not to fear: ZBrush can transfer detail from one side of a model to another with a deformation called Smart ReSym. Let's open up SuperAverageMan and expand the Deformation sub-palette. Just for demonstration purposes, sculpt some random shape into one side of the model.

Restoring symmetry

Sometimes you may be working on a model that you intend to be symmetrical, but you forgot to turn on symmetrical sculpting beforehand. Now, you've put all this work into one side and now you are dreading having to redo all that work. Not to fear: ZBrush can transfer detail from one side of a model to another with a deformation called Smart ReSym. Let's open up SuperAverageMan and expand the Deformation sub-palette. Just for demonstration purposes, sculpt some random shape into one side of the model.

Now, we want to get the same detail on the other side. The Smart ReSym button allows you to set which axis you want to mirror. By default, it's on X, and that is the one we want. Now, if you click the button, you see that what it's done is average the two halves to be the same. Usually, this is not what you want it to do; usually you want all the detail from one side to go over to the un-detailed side. So, I'm going to hit Ctrl+Z to undo that. In order to get all this detail from one side to the other, we need to mask the sculpted side to protect it from change.

So let's zoom out a little bit. I am just going to view the model from straight on, and I am going to hit Ctrl and then click and drag a box over one half of the model. So, this is going to create a mask. It's going to preserve what we have sculpted on this side, so it won't change. Now, let's hit Smart ReSym again. You will use Smart ReSym mainly to fix things when you forgot to have Symmetry turned on in the first place. Don't count on in all the time, however. On particularly complicated or dense models, you may have difficulty getting it to work accurately.

The best defense is to keep an eye on symmetry to make sure you have got it set the way you want before you sculpt.
