Icons on the circle will let us adjust the image in size, rotation and even colour. This shows the shortcut circle of Spotlight, and the image you’re painting with. This next step is potentially every so slightly disturbing for newcomers as you’ll see something like this: When you’re ready to paint, press the ON/OFF button to start Spootlight (green, or press shortcut SHIT+Z). There’s a plus/minus button that’ll do that (red). Images need to be added to Spotlight before they can be used. Kev docks the Textures menu on the left hand side of his ZBrush interface for easy access, but that’s optional.
Some are included with ZBrush, feel free to pick the Jelly Beans image for a quick test. Click on the Textures Menu and import images you’d like to draw with. Let’s take a look at Spotlight now, which is the tool that lets us paint with textures on our object. We’ll cover how to turn those into textures in another article. Remember we’re not painting on a texture, but directly on the outside vertices of the object. Make sure to subdivide your model so that we have enough vertex detail (pixols) to paint on. Pick another colour and see that you can paint on your object. To do that, head over to the Color Menu, pick white and select Fill Object. We need to fill the object with a background colour first so that our stokes appear properly. Note that when you pick a colour with the picker on the left, you’ll notice that the whole object changes. Pick a white mat cap instead of the default red one so we can see what we’re going to paint. At the same time, make sure to enable the Rgb button at the top, enabling paint mode. In edit mode, the default is to sculpt on the object, let’s disable by making sure the Zadd button is not highlit. I’ll draw out a new 3D object (a Sphere_3D in this case), then turn it into a real mesh by pressing Make PolyMesh3D on the Tool shelf.
It’s very powerful and yet another fun way for us to project textures onto 3D objects. I remember making notes on the projection painting tool in ZBrush back in 2013, it’s called Spotlight.
