I am new to modelling and sculpting. I am making a model but my zbrush has made a 2d copy of my model (refer to the image). I had saved my model and was loading it through the saved .ZPR file.
Just press Crtl + n (or go up to top navigation, Layer > Clear) ~ This clears the canvas.
You’ve just made a 2d copy of your model, the shortcut for doing that is Shift + s , which can be useful if you want to make comparisons of the same model on screen.
So you’ll know in future if the same thing happens how to fix it.
Good luck ~ Cheers
