Poly Painting in ZBrush
In this article I will describe the process of poly painting your sculpt inside Pixologics ZBrush and techniques we can employ to control and vary the effect.
What is Poly painting and its Pro’s and Con’s
It would be remiss of me not to detail what poly painting is all about and its pros and cons against such programs as substance painter or Photoshop etc
Poly painting in ZBrush is basically a way we can add texture by alphas, images or brushed on colour, but you need to be aware the amount of detail is governed by the resolution of the mesh, because colour is worked out by each vertex so less vertexes or resolution less quality of colour!
Programs such as Substance rely on UVs and can be painted without the loss of quality as your painting on the UV canvas (UV are flattened maps of the subtools!)
Using Polypainting inside ZBrush
Its pretty simple to apply paint to a subtool inside ZBrush just choose a brush (standard) and make sure ZADD and ZSUB are off and then make sure RGB is turned on (if you turn MRGB you will also be painting material) and the RBD intensity slider is on 100%, in order to start the painting fill your model with a base colour just choose a colour from the left pallet and then go to Colour menu top and drop down to fill object now if you change the colour from the colour pallet the subtool will remain the same colour!, now just start painting!
We have the ability to use multiple techniques inside ZBrush to get better results including these:
- Control opacity’s via the RGB intensity slider
- Use alphas
- Use layers to be able to alter colour intensity
- Use images
- Use masking to control our colour
